Hi folks,

I'm interested in hearing some strategies for plotting two histograms on 
the same plot.  My goal is
to visualize and compare two distributions which have similar shapes.

My first attempt was to use alpha, but this isn't well support on PS2 
output driver (surprising)
and I will be including these in a paper, so having a good print output 
format like PS2 or PDF is desired.
PDF seems to work ok, but the alpha model doesn't completely satisfy my 
in areas where the two
plots overlap a good deal.

import pylab, random

d1 = [random.gauss(0, 1) for i in range(100)]
d2 = [random.gauss(1, 1) for i in range(100)]

color = ['r', 'g']
pylab.hist(d1, facecolor='r', edgecolor='black', alpha=0.75)
pylab.hist(d2, facecolor='b', edgecolor='black', alpha=0.75)
pylab.savefig('test.pdf')
pylab.show()




What ideas do other people have?  My thought was to subdivide the plot 
into two subplots, and
plot one distribution on top, and the other on the bottom, but this 
effectively halves my vertical resolution
(I'm already plotting 24 subplots per page).

Thanks,
Dave
