(keeping the discussion on the mailing list) The object you get back have two attributes: "lines" and "arrows". This is just psuedo-code, but it would look something like this: ``` stream = ax.streamplot(..) art3d.linecollection_2d_to_3d(stream.lines, ) for p in stream.arrows: art3d.p

Thanks for the help, but I can't quite see where to add the add_axes code. Here is the code I have been using to plot, the polar plot is a subplot. fig=figure() ax=fig.add_subplot(111, polar=True) ax.set_xticklabels(["E",45,"N",315,"W",225,"S",135]) ax.set_yticklabels([80,70,60,50,40,30,20,10])

Re: [Matplotlib-users] How to plot straight lines on polar plots

I'm embarrassed to see that I neglected to document this, but you can pass a "resolution" keyword argument to add_axes which sets the number of points of interpolation between each pair of data points. Set this to 1 to disable interpolation. This will be documented shortly. Mike jamesf0 wrot

Re: [Matplotlib-users] How to plot straight lines on polar plots

I don't see any elegant way to do that. The easiest way I can think of is to use a derived line2d class. Something like below will work. Others may have better ideas. import matplotlib.lines class Line2DNoInterpolation(matplotlib.lines.Line2D): def recache(self): matplotlib.lines.L

Hi, Is there any way to plot two graphs in two different windows at the same time? The reason for doing this is that I wanted to update a graph automatically in a for loop, but it turned out that the first figure has to closed manually. Any suggestion for that is also greatly appreciated. Best Rega
