 Pie Demo2
 =========
 
-Make a pie charts of varying size - see
-https://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.pie for the
-docstring.
-
-This example shows a basic pie charts with labels optional features,
-like autolabeling the percentage, offsetting a slice with "explode"
-and adding a shadow, in different sizes.
+Make a pie charts using :meth:`.Axes.pie`.
 
+This example demonstrates some pie chart features like labels, varying size,
+autolabeling the percentage, offsetting a slice and adding a shadow.
