In the extended histogram demo:
http://matplotlib.sourceforge.net/examples/pylab_examples/histogram_demo_extended.html?highlight=codex%20hist
Multiple data are shown in parallel with different colors, using a
single hist command. These colors seem to be automatically chosen,
however, and I cannot figure out a way to control them.
The color kwarg description says that it accepts "matplotlib color arg
or sequence of rgba tuples", but giving it a list of rgba tuples
raises an error.
Am I approaching this the wrong way? Has anybody successfully done this?
Example that raises error:
----------------------------------
import pylab as P
mu, sigma = 200, 25
x0 = mu + sigma*P.randn(10000)
x1 = mu + sigma*P.randn(7000)
x2 = mu + sigma*P.randn(3000)
# The following gives a ValueError from to_rgba
n, bins, patches = P.hist([x0,x1,x2], 50, normed=1, histtype='bar',
color=[(.5, 0., 0., 1.), (0., .5, 0., 1.),])
P.show()
