如何从 dataframe 到 plot 在 x 中包含多个列的分组条形图？

Question

This is my first time trying to plot some data in Python. I have a dataframe like this one:

city	zone	category	searches_ok	searches_null
Buenos Aires	Zone1	Books	12	6
Buenos Aires	Zone1	Home	7	0
Buenos Aires	Zone2	Books	5	7
Rosario	Zone7	Home	25	1
Rio de Janeiro	Zone8	Tech	55	3
Rio de Janeiro	Zone9	Books	12	7
Sao Paulo	Zone15	Tech	34	8

How would go about plotting this in a grouped bar chart? I would like for there to be 2 bars (searches_ok and searches_null) for each "combination" of city/zone/category.

Using this:

df_arg.set_index("zone")
df.plot(x="zone", y=["searches_ok","searches_null"]

I was able to plot a graph with both columns, but only for the "Zone" column... How would you go about doing that for each combination of city/zone/category?

Answer 1

Try making your x columns the index:

df.set_index(['city','zone','category']).plot.bar(rot=45)

Output:
