Pie Chart
=========


.. code-block:: python

    import matplotlib.pyplot as plt

    # Pie chart, where the slices will be ordered and plotted counter-clockwise:
    labels = 'Frogs', 'Hogs', 'Dogs', 'Logs'
    sizes = [15, 30, 45, 10]
    explode = (0, 0.1, 0, 0)  # only "explode" the 2nd slice (i.e. 'Hogs')

    fig = plt.figure(figsize=(5, 5), tight_layout=True)
    ax1 = fig.add_subplot(111)
    ax1.pie(sizes, explode=explode, labels=labels, autopct='%1.1f%%',
            shadow=True, startangle=90)
    # If necessary: Equal aspect ratio ensures that pie is drawn as a circle.
    # ax1.axis('equal')
    fig.savefig("pie_chart.png")
