simple x-y plots

[zachcp]

this might be obvious to others but I couldn't find a way to do a simple X-Y plot where two columns of values correspond to X and Y locations. If this is already implemented I would be happy to write an example for the documentation.

This is currently not possible, see also #857
Workaround is to set the column you want to plot against as index, see below for a sine plot example.

In [109]: x = np.arange(-pi, pi, .01)

In [110]: y = np.sin(x)

In [111]: df = pandas.DataFrame({'X': x, 'Y': y})

In [112]: df.set_index('X').plot()

You can now do df.plot(x='X', y='Y') to plot one column versus another
