How to surpress some autopct values plotted on a pie plot

Question

I can create a piechart where each wedges is having its size printed like this:

df = pd.DataFrame({'mass': [0.330, 4.87 , 5.97],
                   'radius': [2439.7, 6051.8, 6378.1]},
                  index=['Mercury', 'Venus', 'Earth'])
plot = df.plot.pie(y='mass', figsize=(5, 5), autopct= '%.2f')

How can I make it print the values only for a subset (say don't print Mercury)?

Answer 1

• Use a lambda function to conditionally place values with autopct. As per matplotlib.pyplot.pie, which is used by pandas.DataFrame.plot.pie, autopct can be None, a str or a callable function.
• See this answer for additional customization options.

df = pd.DataFrame({'mass': [0.330, 4.87 , 5.97],
                   'radius': [2439.7, 6051.8, 6378.1]},
                  index=['Mercury', 'Venus', 'Earth'])

autopct = lambda v: f'{v:.2f}%' if v > 10 else None

plot = df.plot.pie(y='mass', figsize=(5, 5), autopct=autopct)
