-Provides a MATLAB-like plotting framework.
+`matplotlib.pyplot` is a state-based interface to matplotlib. It provides
+a MATLAB-like way of plotting.
 
-:mod:`~matplotlib.pylab` combines pyplot with numpy into a single namespace.
-This is convenient for interactive work, but for programming it
-is recommended that the namespaces be kept separate, e.g.::
+pyplot is mainly intended for interactive plots and simple cases of programmatic
+plot generation::
 
     import numpy as np
     import matplotlib.pyplot as plt
 
-    x = np.arange(0, 5, 0.1);
+    x = np.arange(0, 5, 0.1)
     y = np.sin(x)
     plt.plot(x, y)
 
+The object-oriented API is recommended for more complex plots.
