Text ¶

class tecplot.annotation.Text(uid, frame)[source]¶

Text annotation.

Attributes

`anchor`	Anchor location of this `Text` object.
`angle`	Angle of the text box in degrees.
`attached_map_index`	Index of the attached fieldmap or linemap.
`box`	The frame and area around this `Text` object.
`clipping`	`Clipping` properties of the `Text`
`color`	`Color` of the `Text` object.
`font`	Typeface properties for a `Text` object.

Text.anchor¶

Anchor location of this Text object.

Specify the anchor point, or fixed point, for the text object. As the text object grows or shrinks, the anchor location is fixed, while the rest of the box adjusts to accommodate the new size. (default = TextAnchor.Left)

There are nine possible anchor position points, corresponding to the left, right, and center positions on the headline, midline, and baseline of the text box.

Example showing how to set the anchor of a Text object:

>>> text = frame.add_text('abc')
>>> text.anchor = tecplot.constant.TextAnchor.Center

See also

Text.position

Type:: TextAnchor

Text.angle¶

Angle of the text box in degrees.

The text angle is the orientation of the text relative to the axis. The angle is measured in degrees counter-clockwise from horizontal. Horizontal text is at zero degrees; vertical text is at 90 degrees.

Example showing how to set the angle of a Text object:

>>> text = frame.add_text('abc')
>>> text.angle = 45

Type:: float (degrees counter-clockwise)

Text.attached_map_index¶

Index of the attached fieldmap or linemap.

Example showing how to set the attached object Index of a Text object:

>>> text = frame.add_text("abc")
>>> text.attached_map_index = 1

Type:: Index or None

Text.box¶

The frame and area around this Text object.

The text box is a rectangular frame drawn around the text. Note that in order to show the text box, you must set TextBox.type to a value other than constant.TextBox.None_.

Example showing how to enable the text box for a Text object:

>>> text = frame.add_text("abc")
>>> text.box.type = tecplot.constant.TextBox.Filled

Type:: annotation.TextBox

Text.clipping¶

Clipping properties of the Text

Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified your text position in the Frame coordinate system, the Text will be clipped to the frame. Default: Clipping.ClipToViewport.

If you have specified the Grid coordinate system, you can choose to clip your Text to the frame or the viewport. The size of the viewport depends on the plot type as follows:

3D Cartesian - The viewport is the same as the frame, so viewport
clipping is the same as frame clipping.

2D Cartesian/XY Line - The viewport is defined by the extents of
the X and Y axes.

Polar Line/Sketch - By default, the viewport is the same as the
frame.

Example showing how to set the clipping of a Text:

>>> text = frame.add_text('abc')
>>> text.clipping = tecplot.constant.Clipping.ClipToFrame

Type:: Clipping

Text.color¶

Color of the Text object.

Default: Color.Black. Example showing how to set the Color of a Text object:

>>> text = frame.add_text("abc")
>>> text.color = tecplot.constant.Color.Blue

Type:: Color

Text.font¶

Typeface properties for a Text object.

Example usage:

>>> text = frame.add_text('abc')
>>> text.font.typeface = 'Times'

Type:: TextFont

Text.line_spacing¶

Spacing between lines in the text box.

Line spacing is dependent on the height of the text and the size unit system in which it is drawn. This example shows how to set the line spacing of a Text object:

>>> text = frame.add_text('abc')
>>> text.line_spacing = 4

Type:: float (default = 1.0)

Text.position¶

Anchor position of the Text.

This is the position of the Text on the Frame and will be $(x,y)$ or $(\theta,r)$ depending on the plot type (Cartesian or polar). This example shows how to set the anchor position of a Text object:

>>> text = frame.add_text("abc")
>>> text.position = (1.0, 2.0)

See also

Text.anchor

Type:: tuple

Text.position_coordinate_system¶

Position coordinate system of the Text object.

The text object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of CoordSys.Frame or CoordSys.Grid

If the position_coordinate_system is CoordSys.Frame, then the size_units property must be Units.Frame or Units.Point.

The text object’s position and text height are adjusted so that it remains identical to its visual appearance in the original coordinate and unit system.

If the size units are Units.Grid and the position coordinate system is changed to CoordSys.Frame, then the size units will be changed to Units.Frame. (default = CoordSys.Frame)

Example showing how to set the position coordinate system for a Text object:

>>> from tecplot.constant import CoordSys
>>> text = frame.add_text("abc")
>>> text.position_coordinate_system = CoordSys.Grid

Example showing side effect if size units are CoordSys.Grid and the coordinate system is changed to CoordSys.Frame:

>>> from tecplot.constant import CoordSys, Units
>>> text = frame.add_text("abc")
>>> text.font.size_units = Units.Grid
>>> text.position_coordinate_system = CoordSys.Frame
>>> text.position_coordinate_system
CoordSys.Frame
>>> text.font.size_units
Units.Frame

Type:: CoordSys

Text.scope¶

The Scope (local or global) of the Text.

Annotations with local scope are displayed only in the frame in which they are created. If the annotation is defined as having global scope, it will appear in all “like” frames. That is, those frames using the same data set as the one in which the annotation was created. (default: Scope.Local)

Example showing how to set the scope of a Text object:

>>> text = frame.add_text("abc")
>>> text.scope = tecplot.constant.Scope.Global

Type:: Scope

Text.text_string¶

The text to be displayed in a text box.

You can embed Greek, Math, and User-defined characters into English-font strings by enclosing them with text formatting tags, together with the keyboard characters.

The text formatting tags and their effects are as follows. Format tags are not case sensitive and may be either upper or lower case:

… - Boldface

… - Italic

<verbatim>…</verbatim> - Verbatim

… - Subscripts

… - Superscripts

<greek>…</greek> - Greek font.

<math>…</math> - Math font.

<userdef>…</userdef> - User-defined font.

<helvetica>…</helvetica> - Helvetica font.

<times>…</times> - Times font.

<courier>…</courier> - Courier font.

Not all fonts have Bold and/or Italic variants. For fonts that do not have these styles, the and/or tags may have no effect.

Embedding and escaping special characters work only in English-font text; they have no effect in text created in Greek, Math, or User-defined character sets.

You can produce subscripts or superscripts by enclosing any characters with … or …, respectively. Tecplot 360 has only one level of superscripts and subscripts. Expressions requiring additional levels must be created by hand using multiple text objects. If you alternate subscripts and superscripts, Tecplot 360 positions the superscript directly above the subscript. To produce consecutive superscripts, enclose all superscript characters in a single pair of tags.

To insert a tag into text literally, precede the first angle bracket with a backslash (“”). To insert a backslash in the text, just type two backslashes (”"). This example shows how to set the text string of a Text object:

>>> text = frame.add_text('abc')
>>> text.text_string
'abc'
>>> text.text_string ='def'
>>> text.text_string
'def'

Type:: str

Text.type¶

Normal or LaTeX text type setting.

Possible values are TextType.Regular or TextType.LaTeX:

>>> text = frame.add_text(r'\alpha')
>>> text.type = TextType.LaTeX

class tecplot.annotation.Circle(uid, frame)[source]¶

A circle annotation attached to a Frame.

See also

Frame.add_circle()

import tecplot as tp
from tecplot.constant import *

frame = tp.active_frame()

circle0 = frame.add_circle((40, 50), 12, CoordSys.Frame)
circle1 = frame.add_circle((50, 50), 12, CoordSys.Frame)
circle2 = frame.add_circle((60, 50), 12, CoordSys.Frame)

circle0.fill_color = Color.Magenta
circle1.fill_color = Color.Yellow

`scope`	Display annotation in all frames with the same data.
`type`	The type of this annotation (read-only).

Circle.attached_map_index¶

Index to the associated fieldmap or linemap.

This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable anno:

>>> anno.attached_map_index = plot.fieldmap(2).index

Type:: Index or None

Circle.clipping¶

Clip geometry to the axes or frame for 2D plots.

Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified the position in the Frame coordinate system, the Annotations will be clipped to the frame. Default: Clipping.ClipToViewport.

If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:

3D Cartesian - The viewport is the same as the frame, so viewport
clipping is the same as frame clipping.

2D Cartesian/XY Line - The viewport is defined by the extents of
the X and Y axes.

Polar Line/Sketch - By default, the viewport is the same as the
frame.

Warning

For 3D and line plots the viewport is the same as the frame and so clipping to the viewport or the frame will have no apparent affect. In cartesian 2D plots, clipping to the axes (Clipping.ClipToViewport) is only available when the position coordinate system is CoordSys.Grid.

Example of clipping a circle to the frame:

>>> from tecplot.constant import Clipping, CoordSys
>>> geom = frame.add_circle((0.5, 0.5), 0.55, CoordSys.Grid)
>>> geom.clipping = Clipping.ClipToFrame

Type:: Clipping

Circle.color¶

Line Color.

This example shows how to change the edge or line Color to red:

>>> from tecplot.constant import Color, CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.color = Color.Red

Type:: Color

Circle.draw_order¶

Draw before or after the data.

Annotations can be drawn either before or after the data. If a geometry or image is drawn before the data, the plot layers, such as mesh, contour lines, etc. will be drawn on top of the geometry. Otherwise, the annotation will be drawn last, potentially obscuring the data.

Note

Tecplot 360 draws all geometries and images first, in the order they were added, then all text.

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import DrawOrder
>>> anno.draw_order = DrawOrder.BeforeData

Type:: constant.DrawOrder

Circle.fill_color¶

Background fill color.

This example shows how to change the area fill Color to red. To turn off filling the geometry, set this attribute to None:

>>> from tecplot.constant import Color, CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.fill_color = Color.Red

Type:: constant.Color

Circle.line_pattern¶

Pattern used for drawing lines or edges.

This example shows how to change the line pattern:

>>> from tecplot.constant import CoordSys, LinePattern
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.line_pattern = LinePattern.DashDot

Type:: LinePattern

Circle.line_thickness¶

Thickness of lines or edges.

This example shows how to change the line thickness:

>>> from tecplot.constant import CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.line_thickness = 4.0

Type:: float

Circle.macro_function¶

An associated macro function.

All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

running a macro file that contains the required macro functions
including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

Example usage assuming an annotation variable anno:

>>> anno.macro_function = 'MYMACROFUNCTION'

To run this function from PyTecplot it is neccessary to pass the function to a call to macro.execute_function():

>>> tecplot.macro.execute_function(anno.macro_function)

Type:: str

Circle.num_points¶

Number of points to use when creating the curved shape.

This is the number of segments along the edge plus one. Example usage:

>>> from tecplot.constant import CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.num_points = 300

Type:: int

Circle.pattern_length¶

Length of the line pattern.

This example shows how to change the pattern length:

>>> from tecplot.constant import CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.pattern_length = 1.2

Type:: float

Circle.position¶

Location on the Frame.

This is the origin of the annotation and will be $(x,y)$ or $(\theta,r)$ depending on the plot type. Example usage assuming an annotation variable anno:

>>> anno.position = (3, 4)

Type:: tuple

Circle.position_coordinate_system¶

Position coordinate system.

The object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of CoordSys.Frame or CoordSys.Grid:

CoordSys.Frame: The geometry is always displayed at constant size and position when you zoom in or out of the plot.

CoordSys.Grid: The geometry resizes and moves with the data grid. However, the geometry remains fixed when you rotate the plot. Changing the center of rotation may cause the geometry to move.

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import CoordSys
>>> anno.position_coordinate_system = CoordSys.Frame

Type:: CoordSys

Circle.radius¶

Length of the radius.

This will be in the coordinate system specified by Circle.position_coordinate_system. This example creates a circle of radius 5 and then doubles it to 10 later:

>>> from tecplot.constant import CoordSys
>>> geom = frame.add_circle((20, 30), 5, CoordSys.Frame)
>>> geom.radius = 10

Type:: float

Circle.scope¶

Display annotation in all frames with the same data.

Annotations with local scope are displayed only in the Frame in which they are created. If it is defined as having global scope, it will appear in all “like” frames. That is, those frames using the same data set as the one in which the annotation was created. (default: Scope.Local)

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import Scope
>>> anno.scope = Scope.Global

Type:: Scope

Circle.type¶

The type of this annotation (read-only).

This is the generic type information for geometry and image annotations. This is a read-only parameter and is used, in combination with position_coordinate_system to determine the actual return types of the iterators Frame.geometries() and Frame.images():

>>> frame.add_image('image.png', (1, 1), 5)
>>> frame.add_circle((0,0), 1, CoordSys.Grid)
>>> frame.add_square((0,0), 1, CoordSys.Grid)
>>> for anno in frame.images():
...     print(anno.type)
...
GeomType.Image
>>> for anno in frame.geometries():
...     print(anno.type)
...
GeomType.Circle
GeomType.Square

Type:: GeomType

Ellipse ¶

class tecplot.annotation.Ellipse(uid, frame)[source]¶

`size`	Size $(h_{axis}, v_{axis})$ of the ellipse.
`type`	The type of this annotation (read-only).

Ellipse.attached_map_index¶

Index to the associated fieldmap or linemap.

This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable anno:

>>> anno.attached_map_index = plot.fieldmap(2).index

Type:: Index or None

Ellipse.clipping¶

Clip geometry to the axes or frame for 2D plots.

Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified the position in the Frame coordinate system, the Annotations will be clipped to the frame. Default: Clipping.ClipToViewport.

If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:

3D Cartesian - The viewport is the same as the frame, so viewport
clipping is the same as frame clipping.

2D Cartesian/XY Line - The viewport is defined by the extents of
the X and Y axes.

Polar Line/Sketch - By default, the viewport is the same as the
frame.

Warning

For 3D and line plots the viewport is the same as the frame and so clipping to the viewport or the frame will have no apparent affect. In cartesian 2D plots, clipping to the axes (Clipping.ClipToViewport) is only available when the position coordinate system is CoordSys.Grid.

Example of clipping a circle to the frame:

>>> from tecplot.constant import Clipping, CoordSys
>>> geom = frame.add_circle((0.5, 0.5), 0.55, CoordSys.Grid)
>>> geom.clipping = Clipping.ClipToFrame

Type:: Clipping

Ellipse.color¶

Line Color.

This example shows how to change the edge or line Color to red:

>>> from tecplot.constant import Color, CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.color = Color.Red

Type:: Color

Ellipse.draw_order¶

Draw before or after the data.

Annotations can be drawn either before or after the data. If a geometry or image is drawn before the data, the plot layers, such as mesh, contour lines, etc. will be drawn on top of the geometry. Otherwise, the annotation will be drawn last, potentially obscuring the data.

Note

Tecplot 360 draws all geometries and images first, in the order they were added, then all text.

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import DrawOrder
>>> anno.draw_order = DrawOrder.BeforeData

Type:: constant.DrawOrder

Ellipse.fill_color¶

Background fill color.

This example shows how to change the area fill Color to red. To turn off filling the geometry, set this attribute to None:

>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.line_thickness = 4.0

Type:: float

Ellipse.macro_function¶

An associated macro function.

All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

running a macro file that contains the required macro functions
including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

Example usage assuming an annotation variable anno:

>>> anno.macro_function = 'MYMACROFUNCTION'

To run this function from PyTecplot it is neccessary to pass the function to a call to macro.execute_function():

>>> tecplot.macro.execute_function(anno.macro_function)

Type:: str

This example shows how to change the pattern length:

>>> from tecplot.constant import CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.pattern_length = 1.2

Type:: float

Ellipse.position¶

Location on the Frame.

This is the origin of the annotation and will be $(x,y)$ or $(\theta,r)$ depending on the plot type. Example usage assuming an annotation variable anno:

>>> anno.position = (3, 4)

Type:: tuple

Ellipse.position_coordinate_system¶

Position coordinate system.

The object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of CoordSys.Frame or CoordSys.Grid:

CoordSys.Frame: The geometry is always displayed at constant size and position when you zoom in or out of the plot.

CoordSys.Grid: The geometry resizes and moves with the data grid. However, the geometry remains fixed when you rotate the plot. Changing the center of rotation may cause the geometry to move.

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import CoordSys
>>> anno.position_coordinate_system = CoordSys.Frame

Type:: CoordSys

Ellipse.scope¶

Display annotation in all frames with the same data.

Annotations with local scope are displayed only in the Frame in which they are created. If it is defined as having global scope, it will appear in all “like” frames. That is, those frames using the same data set as the one in which the annotation was created. (default: Scope.Local)

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import Scope
>>> anno.scope = Scope.Global

Type:: Scope

Ellipse.size¶

Size $(h_{axis}, v_{axis})$ of the ellipse.

This is the horizontal and vertical axis lengths of the ellipse and will be in the coordinate system specified by Ellipse.position_coordinate_system. This example creates an ellipse with $(h_{axis}, v_{axis})$ of $(5, 10)$ and changes it to $(10, 20)$ later:

>>> from tecplot.constant import CoordSys
>>> geom = frame.add_ellipse((50, 50), (5, 10), CoordSys.Frame)
>>> geom.size = (10, 20)

Type:: tuple

Ellipse.type¶

The type of this annotation (read-only).

This is the generic type information for geometry and image annotations. This is a read-only parameter and is used, in combination with position_coordinate_system to determine the actual return types of the iterators Frame.geometries() and Frame.images():

>>> frame.add_image('image.png', (1, 1), 5)
>>> frame.add_circle((0,0), 1, CoordSys.Grid)
>>> frame.add_square((0,0), 1, CoordSys.Grid)
>>> for anno in frame.images():
...     print(anno.type)
...
GeomType.Image
>>> for anno in frame.geometries():
...     print(anno.type)
...
GeomType.Circle
GeomType.Square

Type:: GeomType

Rectangle ¶

class tecplot.annotation.Rectangle(uid, frame)[source]¶

A rectangle annotation attached to a Frame.

Frame.add_rectangle()

import tecplot as tp
from tecplot.constant import *

frame = tp.active_frame()

rectangle0 = frame.add_rectangle((40, 45), (20, 12), CoordSys.Frame)
rectangle1 = frame.add_rectangle((50, 50), (20, 16), CoordSys.Frame)
rectangle2 = frame.add_rectangle((60, 55), (20, 20), CoordSys.Frame)

rectangle0.fill_color = Color.Magenta
rectangle1.fill_color = Color.Yellow
rectangle2.fill_color = Color.Cyan

tp.export.save_png('rectangle.png', 600)

Attributes

`attached_map_index`	Index to the associated fieldmap or linemap.
`clipping`	Clip geometry to the axes or frame for 2D plots.
`color`	Line `Color`.
`draw_order`	Draw before or after the data.
`fill_color`	Background fill color.
`line_pattern`	Pattern used for drawing lines or edges.
`line_thickness`	Thickness of lines or edges.
`macro_function`	An associated macro function.
`pattern_length`	Length of the line pattern.
`position`	Location on the `Frame`.
`position_coordinate_system`	Position coordinate system.
`scope`	Display annotation in all frames with the same data.
`size`	Size $(width, height)$ of the rectangle.
`type`	The type of this annotation (read-only).

Rectangle.attached_map_index¶

Index to the associated fieldmap or linemap.

This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable anno:

>>> anno.attached_map_index = plot.fieldmap(2).index

Type:: Index or None

Rectangle.clipping¶

Clip geometry to the axes or frame for 2D plots.

Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified the position in the Frame coordinate system, the Annotations will be clipped to the frame. Default: Clipping.ClipToViewport.

If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:

3D Cartesian - The viewport is the same as the frame, so viewport
clipping is the same as frame clipping.

2D Cartesian/XY Line - The viewport is defined by the extents of
the X and Y axes.

Polar Line/Sketch - By default, the viewport is the same as the
frame.

Warning

For 3D and line plots the viewport is the same as the frame and so clipping to the viewport or the frame will have no apparent affect. In cartesian 2D plots, clipping to the axes (Clipping.ClipToViewport) is only available when the position coordinate system is CoordSys.Grid.

Example of clipping a circle to the frame:

>>> from tecplot.constant import Clipping, CoordSys
>>> geom = frame.add_circle((0.5, 0.5), 0.55, CoordSys.Grid)
>>> geom.clipping = Clipping.ClipToFrame

Type:: Clipping

Rectangle.color¶

Line Color.

This example shows how to change the edge or line Color to red:

>>> from tecplot.constant import Color, CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.color = Color.Red

Type:: Color

Rectangle.draw_order¶

Draw before or after the data.

Annotations can be drawn either before or after the data. If a geometry or image is drawn before the data, the plot layers, such as mesh, contour lines, etc. will be drawn on top of the geometry. Otherwise, the annotation will be drawn last, potentially obscuring the data.

Note

Tecplot 360 draws all geometries and images first, in the order they were added, then all text.

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import DrawOrder
>>> anno.draw_order = DrawOrder.BeforeData

Type:: constant.DrawOrder

Rectangle.fill_color¶

Background fill color.

This example shows how to change the area fill Color to red. To turn off filling the geometry, set this attribute to None:

>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.fill_color = Color.Red

Type:: constant.Color

Type:: LinePattern

Rectangle.line_thickness¶

Thickness of lines or edges.

This example shows how to change the line thickness:

>>> from tecplot.constant import CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.line_thickness = 4.0

Type:: float

Rectangle.macro_function¶

An associated macro function.

All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

running a macro file that contains the required macro functions
including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

Example usage assuming an annotation variable anno:

>>> anno.macro_function = 'MYMACROFUNCTION'

To run this function from PyTecplot it is neccessary to pass the function to a call to macro.execute_function():

>>> tecplot.macro.execute_function(anno.macro_function)

Type:: str

Polyline3D.attached_map_index¶

Index to the associated fieldmap or linemap.

This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable anno:

>>> anno.attached_map_index = plot.fieldmap(2).index

Type:: Index or None

Polyline3D.color¶

Line Color.

This example shows how to change the edge or line Color to red:

>>> geom.color = Color.Red

Type:: Color

Polyline3D.fill_color¶

Background fill color.

This example shows how to change the area fill Color to red. To turn off filling the geometry, set this attribute to None:

>>> from tecplot.constant import Color, CoordSys
>>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
>>> geom.fill_color = Color.Red

Type:: constant.Color

>>> geom.line_thickness = 4.0

Type:: float

Polyline3D.macro_function¶

An associated macro function.

All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

running a macro file that contains the required macro functions
including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

Example usage assuming an annotation variable anno:

>>> anno.macro_function = 'MYMACROFUNCTION'

To run this function from PyTecplot it is neccessary to pass the function to a call to macro.execute_function():

>>> tecplot.macro.execute_function(anno.macro_function)

Annotations with local scope are displayed only in the Frame in which they are created. If it is defined as having global scope, it will appear in all “like” frames. That is, those frames using the same data set as the one in which the annotation was created. (default: Scope.Local)

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import Scope
>>> anno.scope = Scope.Global

Type:: Scope

Polyline3D.type¶

The type of this annotation (read-only).

This is the generic type information for geometry and image annotations. This is a read-only parameter and is used, in combination with position_coordinate_system to determine the actual return types of the iterators Frame.geometries() and Frame.images():

>>> frame.add_image('image.png', (1, 1), 5)
>>> frame.add_circle((0,0), 1, CoordSys.Grid)
>>> frame.add_square((0,0), 1, CoordSys.Grid)
>>> for anno in frame.images():
...     print(anno.type)
...

>>> multi_polyline.arrowhead.attachment = ArrowheadAttachment.AtEnd
>>> multi_polyline.arrowhead.style = ArrowheadStyle.Filled

Type:: Arrowhead

MultiPolyline2D.attached_map_index¶

Index to the associated fieldmap or linemap.

This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable anno:

>>> anno.attached_map_index = plot.fieldmap(2).index

Type:: Index or None

MultiPolyline2D.clipping¶

Clip geometry to the axes or frame for 2D plots.

Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified the position in the Frame coordinate system, the Annotations will be clipped to the frame. Default: Clipping.ClipToViewport.

If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:

3D Cartesian - The viewport is the same as the frame, so viewport
clipping is the same as frame clipping.

2D Cartesian/XY Line - The viewport is defined by the extents of
the X and Y axes.

Polar Line/Sketch - By default, the viewport is the same as the
frame.

Warning

For 3D and line plots the viewport is the same as the frame and so clipping to the viewport or the frame will have no apparent affect. In cartesian 2D plots, clipping to the axes (Clipping.ClipToViewport) is only available when the position coordinate system is CoordSys.Grid.

Example of clipping a circle to the frame:

>>> from tecplot.constant import Clipping, CoordSys
>>> geom = frame.add_circle((0.5, 0.5), 0.55, CoordSys.Grid)
>>> geom.clipping = Clipping.ClipToFrame

Type:: Clipping

MultiPolyline2D.color¶

>>> geom.color = Color.Red

Type:: Color

MultiPolyline2D.draw_order¶

Draw before or after the data.

Annotations can be drawn either before or after the data. If a geometry or image is drawn before the data, the plot layers, such as mesh, contour lines, etc. will be drawn on top of the geometry. Otherwise, the annotation will be drawn last, potentially obscuring the data.

Note

Tecplot 360 draws all geometries and images first, in the order they were added, then all text.

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import DrawOrder
>>> anno.draw_order = DrawOrder.BeforeData

Type:: constant.DrawOrder

The object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of CoordSys.Frame or CoordSys.Grid:

CoordSys.Frame: The geometry is always displayed at constant size and position when you zoom in or out of the plot.

CoordSys.Grid: The geometry resizes and moves with the data grid. However, the geometry remains fixed when you rotate the plot. Changing the center of rotation may cause the geometry to move.

>>> from tecplot.constant import ImageResizeFilter
>>> image.resize_filter = ImageResizeFilter.BSpline

Type:: ImageResizeFilter

Image.scope¶

Display annotation in all frames with the same data.

Annotations with local scope are displayed only in the Frame in which they are created. If it is defined as having global scope, it will appear in all “like” frames. That is, those frames using the same data set as the one in which the annotation was created. (default: Scope.Local)

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import Scope
>>> anno.scope = Scope.Global

Type:: Scope

Image.size¶

Displayed image size.

This will be in the coordinates specified by Image.position_coordinate_system. Example usage:

>>> image.size = (40, 20)

Type:: $(width, height)$

Image.type¶

The type of this annotation (read-only).

This is the generic type information for geometry and image annotations. This is a read-only parameter and is used, in combination with position_coordinate_system to determine the actual return types of the iterators Frame.geometries() and Frame.images():

>>> frame.add_image('image.png', (1, 1), 5)
>>> frame.add_circle((0,0), 1, CoordSys.Grid)
>>> frame.add_square((0,0), 1, CoordSys.Grid)
>>> for anno in frame.images():
...     print(anno.type)
...
GeomType.Image
>>> for anno in frame.geometries():
...     print(anno.type)
...
GeomType.Circle
GeomType.Square

Type:: GeomType

Image.width¶

Displayed image width in the coordinate system specified.

The units for width are determined by the position_coordinate_system of the image. This example sets the width to 40% of the Frame:

>>> from tecplot.constant import CoordSys
>>> image.position_coordinate_system = CoordSys.Frame
>>> image.width = 0.4

Type:: float

GeoreferencedImage ¶

class tecplot.annotation.GeoreferencedImage(uid, frame)[source]¶

A Geographic reference image.

A georeferenced can be added to a plot with a call to Frame.add_georeferenced_image(). Placement of the image is controlled by the $(x, y)$ variables of the Frame and the GeoreferencedImage object’s $z$ parameter.

Attributes

`attached_map_index`	Index to the associated fieldmap or linemap.
`macro_function`	An associated macro function.
`scope`	Display annotation in all frames with the same data.
`type`	The type of this annotation (read-only).
`z`	$z$-position of the georeferenced image.

GeoreferencedImage.attached_map_index¶

Index to the associated fieldmap or linemap.

This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable anno:

>>> anno.attached_map_index = plot.fieldmap(2).index

Type:: Index or None

GeoreferencedImage.macro_function¶

An associated macro function.

All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

running a macro file that contains the required macro functions
including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

Example usage assuming an annotation variable anno:

>>> anno.macro_function = 'MYMACROFUNCTION'

To run this function from PyTecplot it is neccessary to pass the function to a call to macro.execute_function():

>>> tecplot.macro.execute_function(anno.macro_function)

Type:: str

GeoreferencedImage.scope¶

Display annotation in all frames with the same data.

Annotations with local scope are displayed only in the Frame in which they are created. If it is defined as having global scope, it will appear in all “like” frames. That is, those frames using the same data set as the one in which the annotation was created. (default: Scope.Local)

Example usage assuming an annotation variable anno:

>>> from tecplot.constant import Scope
>>> anno.scope = Scope.Global

Type:: Scope

GeoreferencedImage.type¶

The type of this annotation (read-only).

This is the generic type information for geometry and image annotations. This is a read-only parameter and is used, in combination with position_coordinate_system to determine the actual return types of the iterators Frame.geometries() and Frame.images():

>>> frame.add_image('image.png', (1, 1), 5)
>>> frame.add_circle((0,0), 1, CoordSys.Grid)
>>> frame.add_square((0,0), 1, CoordSys.Grid)
>>> for anno in frame.images():
...     print(anno.type)
...
GeomType.Image
>>> for anno in frame.geometries():
...     print(anno.type)
...
GeomType.Circle
GeomType.Square

Type:: GeomType

GeoreferencedImage.z¶

$z$-position of the georeferenced image.

This is the $z$ position (typically elevation) of the georeferenced image with respect to the $(x, y, z)$ variables set in the Frame. Example usage:

>>> georefimg.z = 100

Type:: float
