Not directly, but you could do it by hand. hist returns (among other
things) a list of rectangle patches that represent all the bars. You could
set the face/edge color of each of the patches based on the value of the
histogram. This example appears to do what you want:

For the other devs:
This would be easier if hist just returned a collection of rectangles. Why
again does histogram just use a list of rectangles?
