VectorPoints

VectorPoints
is an option to VectorPlot, ListVectorPlot and related functions that determines how many field vectors to draw.
Nonedraw no field vectors
ndraw a regular n×n grid of field vectors
{m,n}draw a regular m×n grid of field vectors
Coarseautomatically chosen coarse set of field vectors
Fineautomatically chosen fine set of field vectors
{p1,p2,...}draw field vectors at the points p1, p2, ...
{{p1,g1},...}draw the field vector at p1 using graphics directive g1
