wxmpl incompatibility with matplotlib 0.98.x

[massimo sandal]

Hi,

Sorry if bothering you. Here we use a software (that I've written) that
is based on wxmpl and matplotlib, among other things. A collegue of mine
noticed a problem when installing it on Windows, with the following error:

   File "hooke.py", line 21, in <module>
     import wxmpl
   File "C:\Python25\lib\site-packages\wxmpl.py", line 26, in <module>
     from matplotlib.axes import PolarAxes, _process_plot_var_args
ImportError: cannot import name PolarAxes

He was using matplotlib 0.98.3 .Downgrading to 0.91 solved the issue.
I remember the same happened when, some month ago, I tried to install
the same software on OS X using what were basically SVN versions of mpl,
labeled "0.98pre" (see http://macinscience.org/?page_id=6 )

I guess you are probably aware of the problem: are you already working
on it :) ? Is there any workaround?

I'd like to help you patching it, if within my skills, but I'd need some
direction on how the mpl API have been updated.

I'm not aware of the problem (but I'm not a regular wxmpl user).

 From 0.91 to 0.98, a major refactoring was done to make it easier to
add new kinds of projections.  So PolarAxes is no longer a special case,
it is just one of many possible non-Cartesian projections.  
Unfortunately to do this, the API had to change in a number of places.  
These are documented in the API_CHANGES file in the "TRANSFORMS
REFACTORING" section.

wxmpl needs to be updated based on those instructions in order to be
compatible with mpl 0.98.  Hopefully that process won't be too
difficult, but it's hard to say without trying.  basemap, a fairly large
mpl toolkit, was able to handle the transition fairly smoothly.

Let me know if I can be of further assistance.

Cheers,
Mike

Are there any news on this front?  Has wxmpl been updated, are there
plans to do so, or is it on hold for now?

Just curious...

I had emailed Ken and he said he intended to fix it.  He didn't give me a time line though.

Hi,
I made some small changes to wxMpl to make it work with matplotlib
0.98, based on matplotlib's API_CHANGES.

As I'm new to both matplotlib and wxMpl (and Python too), I don't know
if it is working properly, but it doesn't print error messages
anymore. The demos from wxMpl seemed to work OK.

The modified file is attached, I hope it helps.
