I'm trying to make a bar-style histogram, along the lines of the last
example figure from the extended histogram demo:
http://matplotlib.sourceforge.net/examples/pylab_examples/histogram_demo_extended.html
in which the several arrays to be histogrammed do not have the same
length. However, I'm getting an error about "setting an array element
with a sequence", even when I just cut-and-paste in the example code.
The previous multi-histogram examples in which the array being plotted
is generated using: x = mu + sigma*randn(1000,3) work fine though.
Am I doing something stupid?
Here's the trace:
In [25]: n, bins, patches = hist( [x0,x1,x2], 10, histtype='bar')
