ts[ts.columns[0]].plot() and ts.columns in general #86

Closed hughesadam87 closed 10 years ago

hughesadam87 commented 10 years ago 
ts[ts.columns[0]].plot()

fails, but

ts._df[ts.columns[0]].plot()

works. Also failing is syntax of iloc[:, 0] and iloc[:, 0:1], both of which produce something at least with _df.

Issue seems to be in the colormapper actually.

Actually, this seems to be an indexing error. ts.columns[0] returns a timespectra, but it doesn't have columns (ie treated like a series or something)

a=ts[ts.columns[0]] a.columns

If ts.columns[0] fix does not correct plotting, just use colormap from pandas instead of our own...

hughesadam87 commented 10 years ago

Fixed, now that Spectrum is being returned.
