Re: [matplotlib-devel] Contouring unstructured triangular grids
Ian, I've added you as a developer, and you should now have SVN write access. (This may require explicitly setting a username in SVN the first time you commit.)

Re: [matplotlib-devel] Bug in stepfilled hist with log y
I've looked now through the source code for axes.hist, and I see where
the problem is. If any value of any bin of the histogram is zero,
then axes.fill fails, as zero is necessarily outside the y boundaries
of the axes for log scale.
Already, a default value of 1e-100 is chosen for the first and last
points given to axes.fill. If you also clean the histogram, replacing
all zero y-values with 1e-100, then the fill succeeds. I see no
downside to this treatment, since the default value has already been
introduced.
The user will still need to choose a reasonable lower limit for the y-axis.
Any objections or concerns?
Cheers,
Jeff

Hi Darren, Any progress on looking at the Qt4editor patch ?

Re: [matplotlib-devel] qt4_editor
No, I'm sorry. Its unfair to you that I am the bottleneck here. I just looked for the patch at http://sourceforge.net/tracker/?func=detail&aid=2981606&group_id=80706&atid=560722 but didn't find it. Is the figureoptions.py file there all that is needed?
