Iso-surfaces

An iso-surface displays a constant value of the contour variable as a surface on your plot. Iso-surfaces require that the data set contains volume zones (IJK-ordered, brick, tetrahedral, or polyhedral zones). You can modify iso-surfaces in the Iso-Surface Details dialog, which you can access by selecting the  button next to the Iso-surfaces toggle in the Plot sidebar. Or you can open the Iso-Surface Details dialog by selecting "Iso-Surfaces" from the Plot menu. Finally, you may right-click an iso-surface in your plot and use the context menu and toolbar to make quick changes to its settings.

The context toolbar appears above the context menu when you right-click an iso-surface. This toolbar allows you to turn on or off the grid, contour, shade, and translucency layers for the selected iso-surface(s). Additionally, you may adjust frequently-used style settings for each layer using the drop-down menu to the right of each, for example selecting a color for the grid (or choosing a variable by which to color it).
