# StreamPoints

StreamPoints
is an option to StreamPlot, ListStreamPlot, and related functions that determines how many streamlines to draw.

## DetailsDetails

• The following settings can be given for StreamPoints:
•  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,g1},...} draw streamlines through using graphics directive {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 , StreamPlot and related functions effectively follow the flow of the vector field forward and backward from each point.
• In the form , the minimum distance d between streamlines is given in ordinary coordinates, and applies in all directions.
• In the form , 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:
