Setting the label parameter in the call to DF.plot alters the DataFrame's index name

[dpk011]

Setting the label parameter in the call to df.plot alters the DataFrame's index name. For example,

df = pd.DataFrame(data=np.random.rand(5,3), index=np.arange(5), columns=['A', 'B', 'C'])
df.index.name='RowNumber'
df.plot(y='B', label='Test')
print df.index.name

Out[1]: Test

See a better example at StackOverflow.

pandas version 0.14.1.

Thanks for the report. The easiest fix would probably be to copy the series. Interested in doing a pull request?
