DOC: consider updating visualization.rst to use plot submethods rather than kind

[shoyer]

Another followup to #9321:

Most of the documentation examples in visualization.rst (the main plotting docs) currently use the kind argument. We should probably switch these to use the plotting submethods instead, to push users in that direction.

Question. I'm using analytics.quant-platform. Plotting submethod does not give me a graph just object. Kind argument works?

In [38]:
import pandas as pd
import numpy as np
%matplotlib inline

df = pd.DataFrame(np.random.rand(10, 2), columns=['a', 'b']).plot(kind='barh')

In [41]:
import pandas as pd
import numpy as np
%matplotlib inline

df = pd.DataFrame(np.random.rand(10, 2), columns=['a', 'b'])

df.plot.bar

Out[38]:
bound method FramePlotMethods.bar of <pandas.tools.plotting.FramePlotMethods object at 0x7f04b10fa908

@MattRijk you need to call the method df.plot.bar(), not df.plot.bar

[MattRijk]

Alright. Works. That's weird i used .bar() a few times and nothing. Thanks
