[matplotlib-devel] new colormap
Hi All, As part of nipy[1] we have a spectral colormap which we use and would like to include it upstream as part of matplotlib. I'm working on a patch but before I submit it, I need some advice on how boilerplate.py should be used. I've made the required additions to _cm.py, pylab.py and boilerplate.py and when I run boilerplate.py it generates a spectral() function as it does for all the other colormaps. My question is, how should the output of boilerplate.py be included into pylab.py? Should I just cut and paste the output, or is there some automagic tool for doing it?

[matplotlib-devel] segfault in dynamic_demo.py
When running examples/dynamic_demo I get a segfault with the following backtrace. Does anyone have any thoughts on what might be causing this? I'm using python 2.4 .4c1 and the latest svn version of mpl/numpy/scipy.

Look at the first few lines of dynamic_demo.py
#!/usr/bin/env python
import pygtk
pygtk.require('2.0')
import gtk
It is using gtk explicitly. Your output indicates you are using ewx

Maybe you are mixing backends and GUI mainloops. Make sure your
backend and GUI agree -- eg examples/dynamic_demo_wx.py

Yep, just cut the stuff below

Thanks, that all seems to have worked fine. I've attached the patch
with this email.
John, I was wondering if I have svn write access. I seem to recall I
had it a year or two ago, but I can't find any evidence to back this
up, so maybe I'm mistaken. Could you check for me?
Cheers,
Tim

A few months ago I purged everyone who had not made a commit in a year or so and maybe you were removed then (and posted here to this effect). In general, I don't mind adding people and certainly welcome the relief of not having to manage patches, but the devel list had grown to long. Why don't we manage this submission through the existing devels, and if the patches become fast and furious, I'm more than happy to (re)add you.

In addition to the files you modified, you should consider CHANGELOG and API_CHANGES. The former for non-trivial commits, the latter for API_CHANGES. With this commit, I made an entry to CHANGELOG.
