-MATLAB and pylab allow you to use setp and get to set and get
+The pyplot interface allows you to use setp and getp to set and get
 object properties, as well as to do introspection on the object
 
-set
+set:
     To set the linestyle of a line to be dashed, you can do
 
-      >>> line, = plot([1,2,3])
-      >>> setp(line, linestyle='--')
+      >>> line, = plt.plot([1,2,3])
+      >>> plt.setp(line, linestyle='--')
 
     If you want to know the valid types of arguments, you can provide the
     name of the property you want to set without a value
 
-      >>> setp(line, 'linestyle')
+      >>> plt.setp(line, 'linestyle')
           linestyle: [ '-' | '--' | '-.' | ':' | 'steps' | 'None' ]
 
     If you want to see all the properties that can be set, and their
     possible values, you can do
 
-        >>> setp(line)
+        >>> plt.setp(line)
 
     set operates on a single instance or a list of instances.  If you are
     in query mode introspecting the possible values, only the first
     instance in the sequence is used.  When actually setting values, all
     the instances will be set.  e.g., suppose you have a list of two lines,
     the following will make both lines thicker and red
 
-        >>> x = arange(0,1.0,0.01)
-        >>> y1 = sin(2*pi*x)
-        >>> y2 = sin(4*pi*x)
-        >>> lines = plot(x, y1, x, y2)
-        >>> setp(lines, linewidth=2, color='r')
+        >>> x = np.arange(0,1.0,0.01)
+        >>> y1 = np.sin(2*np.pi*x)
+        >>> y2 = np.sin(4*np.pi*x)
+        >>> lines = plt.plot(x, y1, x, y2)
+        >>> plt.setp(lines, linewidth=2, color='r')
 
 
 get:
 
     get returns the value of a given attribute.  You can use get to query
     the value of a single attribute
 
-        >>> getp(line, 'linewidth')
+        >>> plt.getp(line, 'linewidth')
             0.5
 
     or all the attribute/value pairs
