PlotPoints

PlotPoints
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 specifies different numbers of initial sample points for each successive direction.

Adaptive procedures controlled by MaxRecursion are used to choose more sample points.

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:

Use 10 points in each direction:

Out[1]=
