Here is a first pieplot example using python and the panda library.
Warning!
Pieplots are a highly unadvised way to represent data. Read the intro of the pieplot section to learn more.
# library import pandas as pd # --- dataset 1: just 4 values for 4 groups: df = pd.DataFrame([8,8,1,2], index=['a', 'b', 'c', 'd'], columns=['x']) # make the plot df.plot(kind='pie', subplots=True, figsize=(8, 8))
With Panda you can easily make 2 pieplots for 2 groups:
# library import pandas as pd # --- dataset 2: 3 columns and rownames df = pd.DataFrame({'var1':[8,3,4,2], 'var2':[1,3,4,1]}, index=['a', 'b', 'c', 'd'] ) # make the multiple plot df.plot(kind='pie', subplots=True, figsize=(16,8))
