Generate a pie plot.
A pie plot is a proportional representation of the numerical data in a column. This function wraps matplotlib.pyplot.pie()
for the specified column. If no column reference is passed and subplots=True
a pie plot is drawn for each numerical column independently.
Label or position of the column to plot. If not provided, subplots=True
argument must be passed.
Keyword arguments to pass on to DataFrame.plot()
.
A NumPy array is returned when subplots is True.
Examples
In the example below we have a DataFrame with the information about planetâs mass and radius. We pass the âmassâ column to the pie function to get a pie plot.
>>> 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))
>>> plot = df.plot.pie(subplots=True, figsize=(11, 6))
