PlotPoints

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

Details

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.

Examples

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:
