# StreamPoints

 StreamPoints is an option to StreamPlot, ListStreamPlot and related functions that determines how many streamlines to draw.
 None draw no streamlines n draw at most n streamlines Automatic automatically chosen streamlines Coarse automatically chosen coarse set of streamlines Fine automatically chosen fine set of streamlines {p1,p2,...} draw streamlines through the points p1, p2, ... {{p1,g1},...} draw streamlines through pi using graphics directive gi {spec,d} specify a minimum distance between streamlines {spec,{dstart,dend}} specify minimum distances at start and end {spec,dspec,len} specify a maximum length for any streamline
• When explicit initial points are given in the form {p1, p2, ...}, StreamPlot and related functions effectively follow the flow of the vector field forward and backward from each point.
• In the form {spec, d}, the minimum distance d between streamlines is given in ordinary coordinates, and applies in all directions.
• In the form {spec, d, len}, len gives the total length of the streamlines to generate forward and backward from each explicit initial point specified. The length len is measured in ordinary coordinates.
• The parameters d and len can be specified in the form Scaled[s], representing a fraction of the diagonal of the whole plot.
Use different numbers of streamlines:
Specify streamlines that go through a set of seed points:
