Histogram with multiple data

Hi,

I'm trying to add label to a histogram with multiple data. The doc says "label can also be a sequence of strings" but when I try:

plt.hist([listA, listB, listC], bins=25, histtype='bar', alpha=0.75,rwidth=0.85,label=['A','B','C'])

I got an error:
"AttributeError: 'tuple' object has no attribute 'startswith'"
(for the entire traceback see http://paste.pocoo.org/show/119820/ )

is it me or a bug?

Can I add a legend in another way?

thanks in advance!

-Yva.

Thanks

I guess you're providing an input data with a wrong shape.

aa = np.transpose([listA, listB, listC])
plt.hist(aa, bins=4, histtype='bar',
alpha=0.75,rwidth=0.85,label=['A','B','C'])
