[Matplotlib-users] streamplots in axesgrid

[Yoshi R. <yo...@ro...>]

Hey,

I'm trying to plot streamplots into an axesgrid object with something
like:

fig = pl.figure(1, (13, 20))
grid = AxesGrid(fig, 111,
                nrows_ncols = (3, 2),
                axes_pad = 0.6,
                cbar_location = 'top',
                cbar_mode = 'each',
                cbar_size = '2%',
                cbar_pad = '1%',
               )
[...]
    norm = mpl.colors.LogNorm(vmin=1, vmax=5000)
    im = grid[i].streamplot(XPTS, YPTS, zx, zy,
                            color=zr,
                            arrowsize=.001,
                            norm=norm)
    grid.cbar_axes[i].colorbar(im)
[...]

and then it failes with:

Traceback (most recent call last):
  File "./results.py", line 96, in <module>
    grid.cbar_axes[i].colorbar(im)
  File
"/usr/lib/python2.7/site-packages/mpl_toolkits/axes_grid1/axes_grid.py",
line 85, in colorbar cb = Colorbar(self, mappable,
orientation=orientation, **kwargs) File
"/usr/lib/python2.7/site-packages/mpl_toolkits/axes_grid1/colorbar.py",
line 706, in __init__ mappable.autoscale_None() # Ensure
mappable.norm.vmin, vmax AttributeError: 'StreamplotSet' object has no
attribute 'autoscale_None'

can't I use streamplots in axesgrid? If I comment out the colorbar for
the streamplot colors it works ...
Is this a bug? Is there a right way to do it? Is there a work around?

Many thanks in advance!
