[Matplotlib-users] alpha blending with embeded gtk.

[John G. <jn...@eu...>]

I'm having trouble getting the alpha keyword to do anything when I use 
the OO interface (as per gtk embeded example).

The attached code demonstrates the problem.

With matlab_test() I get alpha blending as expected, with the 
gtk_embed_test() it seems to be ignored.

Aside from this, I'd just like to say what a great package matplotlib 
is.   I've been using it a lot the last week to plot maps -- first I 
started using pcolor to plot hurricane footprints (I'll see if I can get 
the OK to release some of the plots, pcolor produced some wonderful 
pictures with a few lines of code).

Inspired by this I've also been plotting simple maps by creating 
collections of polygons (eg one polygon for each country in the world) + 
associating a value with each polygon.  Again, great pictures in a few 
lines of code + using the collections the speed is pretty good, even 
with 3000+ polygons it was all pretty snappy.

I'll see if I can get an example together -- to do this I'll need to get 
some un-restricted shape files, but I'll see what I can do.

Many thanks for matplotlib.
