yes, both Histogram and Histogram2() launched PyPlot-based
histogramming tool, fixed (including some cosmetics changes in
r48410).

I also worry about duplication of the code. Ideally
histogram.HistFrame and histogram2.HistFrame should have common
superclass. Same probably for histogram2.HistFrame and
profile.ProfileFrame.
