Contours

Contours

is an option for contour plots that specifies the contours to draw.

Details

  • The following settings can be given for Contours:
  • ncontours at n equally spaced levels
    Automaticcontours chosen automatically
    {Automatic,n}at most n contours chosen automatically
    {f1,f2,…}contours at levels fi
    {{f1,gr1},…}contours drawn with graphics directives gri
    funca function to be applied to zmin, zmax to get the list of contours
  • With Automatic settings, "nice" equally spaced contour levels are chosen, whose values minimize the number of digits in their decimal representation.
  • In ContourPlot and ListContourPlot, Contours specifies contour lines.
  • In ContourPlot3D and ListContourPlot3D, Contours specifies contour surfaces.
  • ContourPlot and ContourPlot3D let you give an equation f==g or a list of equations as a way to specify single contours to draw.
