Re: [matplotlib-devel] SpanSelector and figure.subplots_adjust

[Charlie M. <cw...@gm...>]

So this happens with TkAgg and blitting.  Here is the sample script:

#!/usr/bin/env python
import matplotlib; matplotlib.use('TkAgg')
import pylab
from matplotlib.widgets import SpanSelector

fig =3D pylab.figure()
ax =3D fig.add_subplot(111)

ax.plot(pylab.rand(100))
def onselect(vmin, vmax):
    print vmin, vmax

span =3D SpanSelector(ax, onselect, 'horizontal', useblit=3DTrue,
                    rectprops=3Ddict(alpha=3D0.5, facecolor=3D'red') )

pylab.show()

Adjust the subplot params then you will see the distortion.  With 2
subplots the spanselector never visually appears, but the callback is
called.

Thanks,
     Charlie
