area plots are causing my unit tests to fail
I'm using the latest matplotlib and pandas.  If you run the following code, do the legends look right to you?  The unit tests don't like them.

``` python
df = DataFrame(
            np.random.rand(10, 3),
            index=list(string.ascii_letters[:10]))
df.plot(kind='area', subplots=True, sharex=True, legend=True)
```
