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

explains the usage of 2D histograms.
Although it is possible to construct 2D histograms with a variable bin
size, there is no simple way to plot them.
Therefore I would like to request an implementation to imshow that
allows the visualization of 2D histograms with variable bin size. I
imagine a syntax like

imshow(historgram2d, xedges=xedges, yedges=yedges)

where xedges and yedges are the bin edges along the x- and y-axis.

I have attached a short program and its output which constructs a
numpy.historgram2d with variable bin width (xedges=[0,1,3]) and shows
its bin content with imshow.
I would highly appreciate if imshow would be extended to represent the
histogram correctly.
If there is an alternative solution, I would be interested to learn
about it as well.

Kind regards
