[SciPy-Dev] 2D histogram: request for plotting variable bin size

[Frank Breitling]

Hi Sturla,

My experience with pcolor was that is was very slow.
Pcolormesh was significantly faster but compared to imshow is still very 
slow.
However, while imshow produces smooth interpolations between the 
discrete frequencies I didn't find a similar option with pcolormesh and 
so the results were not useful.
You can see it in the imshow and pcolormesh images attached.
