.plot() no longer works on the dataframes.

• HydroFunctions version: 0.1.6

Description

The new dataframe format has the data qualifiers adjacent to the data, so that different columns have different types of data placed together. Now when you try to plot using: my_dataframe.plot() it generates an error.

What I Did

import hydrofunctions as hf
%matplotlib inline
sites = ['01581830', '01589330']
data = hf.NWIS(sites, start_date='2002-01-01', end_date='2005-01-01').get_data()
data.ok

data.df().plot()
-error-

Pandas has no way of converting what is in the column into something it can plot.

Proposed Solution:

Create different functions for creating different kinds of dataframe layout. There is more than one way to organize the data into a dataframe. Create a method for outputting a dataframe that can be plotted automatically.

Perhaps put the qualifiers into an identical dataframe that matches cell for cell with the data.

see issue #26.

Closed with the feature-df-select branch. See commit e3e4d42. Now you can just request the data you want to plot, and it plots fine.

herring = hf.NWIS('01585219', 'iv', period='P5D')
herring.df('discharge').plot()

This should work fine. Although it gives a warning about stripping off the UTC time zone info.
