I think this needs some clean-up:

"The latest matplotlib-0.87.7 for windows was compiled with numpy 1.0
final. Please make sure you are not using the latest numpy-1.0."

On which subject, "What's new" starts:

What's new in matplotlib 0.83

rather than the 0.87.7

basemap compile problem


I have a fresh update of basemap from svn and a clean build dir, and I
am getting a build error

yes, that is a bit out of date....  If you would like to help here,
the file htdocs/whats_new.html.template is in the htdocs svn
repository.  The format of what's new is a python dictionary where the
keys are version numbers and the values are tuples of (header,
description) tuples.

If you could take some time to peruse the CHANGELOG file and update
some entries in the what's new dictionary, I will apply them to the
svn code and update the web page.  

versioninfo['0.87.5'] = (
  ("aspect handling", """\
Excellent support for axes aspect handling, with aspect='equal' or
  aspect=1.5 or aspect='norm' passed to an Axes or Subplot

Yes, this works.

But now I am getting a traceback with basemap + mpl svn in contour
with the attached file.  I don't know if this is a bug in the example
code or in the contour module (it appears tcolors is not getting set
because the changed method is not being called, but I only looked at
it briefly)

A question about cbook.is_string_like

Hello everybody,

I'm in the process of replacing R by matplotlib to plot all of our charts.

I'm hacking the PDF backend because I need this format to import
charts in ConTeXt (this is TeX macro package, similar to LaTeX, we use
to produce PDF reports).

My first question, very basic, is why function is_string_like, in
module cbook, doesn't simply

   return isinstance(s, types.StringTypes)

instead of

   try: obj + ''
   except (TypeError, ValueError): return 0
   return 1

Thanks for your work,

Nicolas

I am all for a good PDF backend, but you should be aware that under
unices you can tell matplotlib to use a distiller, as illustrated in:
