XY Entities

4 - 6 XY Entities

An XY Entity plot depicts a set of entities for a single X-axis and Y-axis variable pair. For example, you can compare oil production for a selected set of wells in one plot.

You can un-dock the Plot Controls sidebar by dragging its title bar to a new position. To put the Plot Controls back on the side of the workspace, double-click on its title bar (the region that displays the words “Plot Controls”). Or you can drag its title bar to either side of the workspace and let go, and it will snap into place.

For all XY Entities plots (including RFT), if XY fracture data is detected, the fracture data will display in a separate dotted line below the matrix data. XY fracture data is detected if the number of XY points is exactly twice the grid K dimension, or if an MFTAG variable is found when reading RFT data.

To create an XY Entities plot, load an XY data file and choose “XY Entities” from the Pot Type menu at the bottom of the sidebar.

The sidebar for XY Entity plots has the following options:

• Lines and Symbols Use the Lines and Symbols controls to customize your XY plot.

• Reload Click the Reload button at any time to refresh your data set.

The Reload control works only if “Enable Reload” was selected on the Load XY Data dialog during the file loading process. Refer to Section 4 - 1 “Loading XY Data” for additional information.

• Filter To manage the entities shown in the list, use the Filter button. Refer to Section 7 - 1 “Filtering” for more information.

• Variables Use the Variables section of the sidebar to specify the axes variable assignments.

• X-axis Use the X menu to choose the X-axis variable. You can choose only one X-axis variable.

• Y-axis Use the Y-axis box to choose a Y-axis variable. You can choose only one Y-axis variable.

• Zoom Lock The lock icon next to the X menu can be engaged to hold the active frame’s X-axis range (zoom) when switching to XY Subsets or XY Variables plots. It is disengaged automatically when the X-axis variable is changed.

• Scrolling Use the animation control buttons to scroll through the available Y-axis variables. See Paging: Animation and Scrolling Controls for additional information.

• Entities The Entities box allows you to select wells and other structures to display.

• Sum Toggling-on “Sum” allows you to sum the variable being plotted for all entities that have been chosen.

• Avg Toggle-on “Avg” to show the average value for all chosen entities.

• Ignore 0 Values When displaying averages, toggle-on to ignore zero values.

When you have either Sum or Avg toggled-on, Tecplot RS cannot display comparison data. See Chapter 10: “Comparing XY Data”.

The variables selected in the Variables section of the sidebar will display for the selected Entity. Click the button to launch an expanded, searchable entity list. This helps for long lists. When you have multiple frames displayed, the selected Y-axis variable displays in the first frame, with subsequent variables in subsequent frames.

• Data Set The Data Set region of the dialog allows you to compare data when you have multiple data files loaded. Refer to Chapter 10: “Comparing XY Data” for additional information.

The settings for “Entity [1-9]” in your RS Variables Files file determines the default styles (for example, line color, and symbol shape) that your plot displays. You can change any of the default styles by either updating the file or changing the settings for “Entity [1-9]” (long variable names) or “ST [1-9]” (short variable names) on the XY Lines page of the Plot Options dialog. Double-click on the line in your plot to bring up the appropriate page of the dialog.
