@@ -2488,78 +2488,77 @@ def pie(self, x, explode=None, labels=None, colors=None,
         x : array
             The input array used to make the pie chart.
 
-        explode: None or array
+        explode : None or array
             If not *None*, is a ``len(x)`` array which specifies the
             fraction of the radius with which to offset each wedge.
 
-        colors: None or array
+        colors : None or array
             A sequence of matplotlib color args through which the pie chart
             will cycle.  If `None`, will use the colors in the currently
             active cycle.
 
-        labels: None or list
+        labels : None or list
             A sequence of strings providing the labels for each wedge
 
-        autopct: None or string or function
+        autopct : None or string or function
             If not *None*, is a string or function used to label the wedges
             with their numeric value.  The label will be placed inside the
             wedge.  If it is a format string, the label will be ``fmt%pct``.
             If it is a function, it will be called.
 
-        pctdistance: float
+        pctdistance : float
             The ratio between the center of each pie slice and the
             start of the text generated by *autopct*.  Ignored if
             *autopct* is *None*; default is 0.6.
 
-        labeldistance: float
+        labeldistance : float
             The radial distance at which the pie labels are drawn
 
-        shadow: bool
+        shadow : bool
             Draw a shadow beneath the pie.
 
-        startangle: None or Offset angle
+        startangle : None or float
             If not *None*, rotates the start of the pie chart by *angle*
             degrees counterclockwise from the x-axis.
 
-        radius: None or float
+        radius : None or float
           The radius of the pie, if *radius* is *None* it will be set to 1.
 
-        counterclock: bool
+        counterclock : bool
             Specify fractions direction, clockwise or counterclockwise.
 
-        wedgeprops: None or dict
+        wedgeprops : None or dict
             Dict of arguments passed to the wedge objects making the pie.
             For example, you can pass in wedgeprops = { 'linewidth' : 3 }
             to set the width of the wedge border lines equal to 3.
             For more details, look at the doc/arguments of the wedge object.
             By default `clip_on=False`.
 
-        textprops: None or dict
+        textprops : None or dict
             Dict of arguments to pass to the text objects.
 
-        center:  list of int
+        center :  list of float
           Center position of the chart. Takes value (0,0) or is a sequence
           of 2 scalars.
 
-        frame: bool
+        frame : bool
             Plot axes frame with the chart if true.
 
-        rotatelabels: bool
+        rotatelabels : bool
             Rotate each label to the angle of the corresponding slice if true.
 
         Returns
         -------
-        patches: list
+        patches : list
             A sequence of :class:`matplotlib.patches.Wedge` instances
 
-        texts: list
+        texts : list
             A is a list of the label :class:`matplotlib.text.Text` instances.
 
-        autotexts: list
+        autotexts : list
             A is a list of :class:`~matplotlib.text.Text` instances for the
-            numeric labels. Is returned only is if parameter *autopct* is
-            not *None*. If *autopct* is *None*, the tuple returned
-            is (patches, texts).
+            numeric labels. Is returned only if parameter *autopct* is
+            not *None*.
