DensityPlot

DensityPlot
makes a density plot of f as a function of x and y.
  • DensityPlot by default generates colorized grayscale output, in which larger values are shown lighter.
  • At positions where f does not evaluate to a real number, holes are left so that the background to the density plot shows through.
  • DensityPlot has attribute HoldAll, and evaluates f only after assigning specific numerical values to x and y.
  • In some cases it may be more efficient to use Evaluate to evaluate f symbolically before specific numerical values are assigned to x and y.
  • The plot is left blank in any regions where f evaluates to None.

  • DensityPlot initially evaluates f at a grid of equally spaced sample points specified by PlotPoints. Then it uses an adaptive algorithm to subdivide at most MaxRecursion times to generate smooth contours.
  • You should realize that since it uses only a finite number of sample points, it is possible for DensityPlot to miss features of your functions. To check your results, you should try increasing the settings for PlotPoints and MaxRecursion.
  • With the setting Mesh->All, DensityPlot draws mesh lines to show all the subdivisions it uses.
  • ColorFunction is supplied with a single argument, given by default by the scaled value of f.
