I'd like to make something in between a box plot  and a histogram. Each histogram would be represented by a single, tall, rectangular patch (like the box in a box plot), and the patch would be subdivided by the bin edges of the histogram. The face color of each sub-patch would replace the bar height in the histogram.
If any of that actually made sense:
* Does this type of plot have a name?
* Is there an easy way to do this in Matplotlib?
* If there isn't an easy way, what would be a good starting point? Initial ideas: 1) Use pcolor or imshow and embed this axes in a larger axes, 2) represent the sub-patches as a PolyCollection.
