如何使用 python 中的交叉表 function 从 dataframe 获得饼图 plot

Question

i am trying to plot a pie chart using crosstab function from 2 columns in a dataframe where until now i am able to plot a bar chart using the below statement.

sample of the dataframe:

pd.crosstab(df['event_location'],df['event_type']).iplot(kind="bar", bins=20, theme="white", title="Event type over Location",xTitle='location', yTitle='Number of person')

my question is how to convert this bar chart into a pie chart?

Answer 1

I guess you are trying to display the number of occurrences for every event type. This simple code will help you plot pie charts per location.

import matplotlib.pyplot as plt
ct = pd.crosstab(df['event_location'],df['event_type'])
ct.plot.pie(subplots=True)
plt.legend(title='XYZ')
plt.show()
