Default color for bar.

[d-cosin]

If no color is defined when calling the bar method, it is returned the following TypeError:

lib/python2.7/site-packages/matplotlib/colors.pyc in to_rgba_array(c, alpha)
    235         return result
    236     # Convert one at a time.
--> 237     result = np.empty((len(c), 4), float)
    238     for i, cc in enumerate(c):
    239         result[i] = to_rgba(cc, alpha)

TypeError: object of type 'float' has no len()

The problem is solved if the color attribute is defined when calling the bar method. Wouldn't be the case of assigning a default color when none is specified by the user?

Interesting. It looks to me like the behavior differs between 2.7 and 3.x maybe. Should be easy enough to fix hopefully. Of course the real TODO here is to write a proper test suite!

This looks like a bug in the pandas.DataFrame.plot method to me; I can no longer pass RGB tuples to it successfully? IDK what's going on there.

I've fixed this error in HEAD (by using a named color instead), and it will go out as part of a new version of the library fairly soon. Thanks for reporting, and sorry it took so long to get to!
