Isosurface (Plot)
Plot a scalar quantity as an Isosurface () plot in 3D. An isosurface plot displays a quantity as a colored set of isosurfaces on which the result has a constant value. The plot can also color isosurfaces based on an independent quantity. You can move the isosurfaces interactively. Add Color Expression, Deformation, Filter, Selection (Plot Attribute), Translation, Transparency, or Visual Effects subnodes as needed. Right-click a 3D Plot Group to add this plot type.
Before plotting, select the Interactive check box to move the isosurfaces defined in this Isosurface node interactively using the slider or by entering a shift in the Shift field. A zero shift represents the original position of the isosurfaces.

Coloring and Style
From the Isosurface type list, choose Surface (the default), to plot isosurface as surfaces, or Filled, to plot isosurfaces as filled volumes. For the filled isosurfaces, it is recommended to use transparency for the plot.
If you chose Surface, select the Level labels check box to add labels for the isosurface levels.
If you chose Filled, the Fill volume outside of isosurface levels check box is selected by default. Clear this check box if you do not want filled volumes for levels above and below the isosurface levels. Also, select the Include interior boundaries check box if you want to include any interior boundaries in the filled isosurface plot.
For coloring the isosurfaces, select one of the following options from the Coloring list:
•
Select Color table (the default) to color the contours using a color table that you choose from the Color table list below.
•
Select Uniform to use a predefined uniform color, or select Custom to define a custom color from the colored list below (on Windows) or by clicking the Color button (on Linux and macOS) and then selecting a color from the color palette.
•
Select Gradient to specify the coloring as a gradient between two colors, which you specify using the Top color and Bottom color lists.
Choose a color table for the isosurfaces from the Color table list.
The Color legend check box is selected by default. Clear it to remove the color legend. Select the Reverse color table or Reverse color gradient check boxes as required.

From the Scale list, choose Linear (the default), Linear symmetric, or Logarithmic.
