RegionFunction |  |
RegionFunction
is an option for plotting functions which specifies the region to include in the plot drawn. |
- The setting RegionFunction->r specifies that a point should be included in the region when r[args] 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.
Plot over an annulus region:
| Out[1]= |  |
| Out[2]= |  |
Region cuts in the radial direction:
| Out[1]= |  |
