({{, (RefLink[StreamPoints, paclet:ref/StreamPoints]) 
is an option to (RefLink[StreamPlot, paclet:ref/StreamPlot]), (RefLink[ListStreamPlot, paclet:ref/ListStreamPlot]), and related functions that determines how many streamlines to draw.}})

OpenersNotesSection(Spacer1)Details

The following settings can be given for (RefLink[StreamPoints, paclet:ref/StreamPoints]):

When explicit initial points are given in the form {(Subscript[p, 1]),(Subscript[p, 2]),…}, (RefLink[StreamPlot, paclet:ref/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 (RefLink[Scaled, paclet:ref/Scaled])[s], representing a fraction of the diagonal of the whole plot.

OpenersPrimaryExamplesSection(Spacer1)Examples  (4)

OpenersExampleSection0(Spacer1)Basic Examples  (2)

Use different numbers of streamlines:

Row[Table[StreamPlot[{-1-x^2+y,1+x-y^2},{x,-3,3},{y,-3,3},StreamPoints->n],{n,5,35,10}]]

Specify streamlines that go through a set of seed points:

points = Tuples[{-2,0,2},2]

StreamPlot[{-1-x^2+y,1+x-y^2},{x,-3,3},{y,-3,3},StreamPoints->points,Epilog->Point[points]]

OpenersExampleSection1(Spacer1)Scope  (2)

Use both automatic and explicit seeding with styles for explicitly seeded streamlines:

StreamPlot[{-1-x^2+y,1+x-y^2},{x,-3,3},{y,-3,3},StreamPoints->{{{{1,0},Red},{{-1,-1},Green},Automatic}}]
