More descriptive ylabel for Series.hist()

[clarkfitzg]

s = pd.Series(np.random.randn(100))
s.plot(kind='hist')
s.hist()

Running s.plot(kind='hist') labels the y axis with the word 'Degree'. A more informative label might be 'count', 'frequency', or 'density'.

Also, it seems strange that s.plot(kind='hist') and s.hist() produce plots with different labels / gridlines.

Looks like this came from PR #7809. cc @sinhrks, @jreback

The name "Frequency" sounds more appropriate to me -- unless normed=True, in which case "Density" would be the right word.

[clarkfitzg]

+1 for 'Frequency'. That would make sense to me if normed=True or not. 'Density' makes me think of a probability density function.

Related to #9093. The reason I've added ylabel is for consistency with kind='kde'. I'm willing to change it if there is better word choice (of course PR is welcome!).

[clarkfitzg]

Looks like kind='kde' labels it with 'Density'.

Closed by #10493. Thanks @clarkfitzg !
