I'd like to make something in between a box plot [1] 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.

I am not quite sure I understand.  


Or maybe something else in the gallery is more like what you want:

I've checked the gallery, but I don't see anything that appears similar. In any case, I ended up hacking together something that works. I've attached an image of what I had in mind (created with the code at the very bottom of this reply).

I ended up using mpl Rectangle objects and stringing them together using a PatchCollection. Maybe there's a more efficient way to do this, but this approach worked well-enough.


Actually, that looks kinda cool.  If anyone is aware of the name for this kind of plot, maybe we could add a new plotting function?
