is an option for plotting functions that specifies the region to include in the plot drawn.
- The setting RegionFunction->r specifies that a point should be included in the region when yields True.
- The arguments supplied to r are as follows:
Plot and ListLinePlot x , y ParametricPlot x, y, u or x, y, u, v RegionPlot x, y ContourPlot and ListContourPlot x, y, f DensityPlot and ListDensityPlot x, y, f ContourPlot3D and ListContourPlot3D x, y, z, f Plot3D, ListPlot3D and ListSurfacePlot3D x, y, z ParametricPlot3D x, y, z, u or x, y, z, u, v RegionPlot3D x, y, z
- Adaptive refinement is typically used to determine the boundaries of the region specified by RegionFunction.
- The boundary of regions defined by RegionFunction is drawn with a style specified by the setting for BoundaryStyle.
