熊猫和Matplotlib-如何更改绘图区域以适合更多X轴文本？

Question

Say I read in this csv file into a pandas dataframe:

File contents:

 Strings, Values, Letters Made up data, 55.0, A with long text strings for index, 125.5, B with long text strings for index, 85.5, B how does one, 1.3, A how does one, 12.3, A change the plot area to, 96.1, B fit all of this text in?, 0.2, B fit all of this text in?, 47.2, B 

Code:

c=pd.read_csv('myfile.csv')

Gives:

  Strings Values Letters 0 Made up data 55.0 A 1 with long text strings for index 125.5 B 2 with long text strings for index 85.5 B 3 how does one 1.3 A 4 how does one 12.3 A 5 change the plot area to 96.1 B 6 fit all of this text in? 0.2 B 7 fit all of this text in? 47.2 B 

I then use groupby to sum the strings:

g=c.groupby(u'Strings').sum()

Giving:

  Values Strings Made up data 55.0 change the plot area to 96.1 fit all of this text in? 47.4 how does one 13.6 with long text strings for index 211.0 

And finally plot like so:

g.plot(kind='bar')

Giving:

As you can see the x axis text is badly cropped. How can I fix this?

Note that I have tried using the rot parameter (eg rot=-45 ) but this is insufficient.

I imagine that a solution might involve setting the plot area but I'm unsure how to do this.
