First of all I just committed a generalized SpanSelector widget that allows for a horizontal or vertical selection. I am running into a problem (and HorizontalSpanSelector suffered from the same problem) that the rect is drawn incorrectly if I adjust the sublot params. Any of the MPL transforms experts know what I need to do? Thanks, Charlie

I guess I should have mentioned TkAgg CVS. I didn't think the problem would be specific to a backend, so I didn't try any others. Also, when I have more than one subplot, nothing is drawn period. - Charlie On 11/9/05, John Hunter <jdh...@ac...> wrote: > >>>>> "Charlie" =3D=3D Charlie Moad <cw...@gm...> writes: > > Charlie> First of all I just committed a generalized SpanSelector > Charlie> widget that allows for a horizontal or vertical > Charlie> selection. > > Charlie> I am running into a problem (and HorizontalSpanSelector > Charlie> suffered from the same problem) that the rect is drawn > Charlie> incorrectly if I adjust the sublot params.

I will have to do more testing, but I am calling figure.subplots_adjust, not adjusting with the widget. This is also through the oo interface. I will try to write a sample script and get back to the list.

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

A challenge to the community! ;)
Run the current cursor.py example with the TkAgg backend. (blitting
should be on)
i.e. python cursor.py -dTkAgg
Why does the blitting not update the entire axis? Any help on this is
greatly appreciated.
Thanks,
Charlie

Awesome, thanks!

Arg! One petty thing after another. Here is a simple script
demonstrating that the last row does not render the SpanSelector, yet
the callback works fine???
------------------------------------
import matplotlib
from matplotlib.widgets import SpanSelector
matplotlib.use('TkAgg')
from pylab import *
s =3D 3
axs =3D [subplot(s,s,i) for i in xrange(1,s**2+1)]
def onselect(x, y): print x, y
[SpanSelector(a, onselect, 'vertical', useblit=3DTrue) for a in axs]
show()
------------------------------------
Any clues as to where to look for this bug? Sorry to be a hassle, but
I need this specifically to embed in a Tk only app.
Thanks,
Charlie
