# pandas.Series.plot.pie

Series.plot.pie(y=None, **kwargs)

  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.

  Parameters:
    y int or label, optional

      Label or position of the column to plot. If not provided, `subplots=True` argument must be passed.

    **kwargs

      Keyword arguments to pass on to `DataFrame.plot()`.

  Returns:
    matplotlib.axes.Axes or np.ndarray of them

      A NumPy array is returned when subplots is True.

    Generate a pie plot for a Series.

  `DataFrame.plot`

    Make plots of a DataFrame.

  Examples

  In the example below we have a DataFrame with the information about planet’s mass and radius. We pass the ‘mass’ 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))
