I first thought of computing histograms in the sense of image processing. 
But there is also the 'histogram' plotting style in gnuplot. If you mean 
this one, then we had to add the histogram style to 
Graphics.Gnuplot.Private.Graph2DType. However since this style has some 
variations and parameters, we would have to check how to support them in a 
Haskellish way.
