Labeling Streamlines in StreamPlot

[member 428835]

Hi PF!

I am trying to label two different sets of streamlines but am having no luck. My code is

StreamPlot[{{y, -x}, {x, y}}, {x, -3, 3}, {y, -3, 3},
 PlotLegends -> LineLegend["graph 1", "graph 2"]]

Thanks!

Try the simpler approach

StreamPlot[{{y, -x}, {x, y}}, {x, -3, 3}, {y, -3, 3},
PlotLegends -> {"graph 1", "graph 2"}]
