控制流线的位置

使用 StreamPoints 为流线提供种子点.

    
Wolfram Language code: pts = Flatten[Table[{{x, y}, Hue[RandomReal[]]}, {x, -1, 1, 0.25}, {y, -1, 1, 0.25}], 1];
Wolfram Language code: StreamPlot[{-y ^ 2, Sin[x]}, {x, -1, 1}, {y, -1, 1}, AspectRatio -> Automatic, StreamPoints -> {pts, Automatic, Scaled[2.3]}, StreamScale -> None, Epilog -> {Blue, PointSize[Medium], Point[pts[[All, 1]]]}]
