is an option for plotting functions that specifies how many initial sample points to use.


  • With a single variable, PlotPoints->n specifies the total number of initial sample points to use.
  • With more than one variable, PlotPoints->n specifies that n initial points should be used in each direction.
  • PlotPoints->{n1,n2,} specifies different numbers of initial sample points for each successive direction.
  • The initial sample points are usually equally spaced.
  • Adaptive procedures controlled by MaxRecursion are used to choose more sample points.


Basic Examples  (4)

Use 10 points in each direction:

MaxRecursion will cause additional sampling beyond the initial 10 points:

Use 50 points along the direction:

Use different numbers of points for different variables:
