我怎样才能 plot 一个 pd.crosstab() 表？

Question

I have a dataframe just like any other, but with two categorical columns.

Just like this:

id    color      size
1     blue       M
2     red        S
3     red        M
4     blue       S
5     yellow     L
6     red        L

And I have the distribution table:

pd.crosstab(df['color'],df['size'], margins=None)

Is there a way of plotting this? (Just like tableau or power BI would)

Answer 1

Though matplotlib and seaborn doesn't allow plotting crosstabs, you can use pandas plot for the same. It would look something like this:

color = ['blue', 'red', 'red', 'blue', 'yellow', 'red']

size = ['M','S','M','S','L','L']

df = pd.DataFrame((color, size), index=['color','size']).T

Crosstab plot
