MeshFunctions

MeshFunctions
is an option for plotting functions that specifies functions to use to determine the placement of mesh divisions.
  • In Plot3D, the default setting MeshFunctions->{#1&, #2&} specifies that meshes corresponding to x and y coordinates should be constructed.
  • With the setting MeshFunctions->{m1, m2, ...}, each function mi defines a family of mesh divisions.
  • By default, the mesh divisions are taken to lie at positions giving equally spaced values of mi[...].
  • The arguments supplied to the mi and the default MeshFunctions settings are as follows:
Plot and ListLinePlotx, y {#1&}
ParametricPlotx, y, u or x, y, u, v {#3&} or {#3&,#4&}
PolarPlot and ListPolarPlot
x, y, , r(#3&)
RegionPlotx, y {#1&,#2&}
ContourPlot and ListContourPlot
x, y, f {}
DensityPlot and ListDensityPlot
x, y, f {#1&,#2&}
ContourPlot3D and ListContourPlot3D
x, y, z, f {#1&,#2&,#3&}
Plot3D and ListPlot3Dx, y, z {#1&,#2&}
ListSurfacePlot3Dx, y, z {#1&,#2&,#3&}
ParametricPlot3Dx, y, z, u or x, y, z, u, v {#4&} or {#4&,#5&}
RegionPlot3Dx, y, z {#1&,#2&,#3&}
  • Each mi effectively defines a foliation.
  • The mi should normally be chosen to be continuous monotonic functions.
