+        r"""Plot a pie chart.
 
         Make a pie chart of array *x*.  The fractional area of each
         wedge is given by x/sum(x).  If sum(x) <= 1, then the values
         of x give the fractional area directly and the array will not
         be normalized.  The wedges are plotted counterclockwise,
         by default starting from the x-axis.
 
-        Keyword arguments:
+        Parameters
+        ----------
+        x : array
+            The input array used to make the pie chart.
 
-          *explode*: [ *None* | len(x) sequence ]
+        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* | color sequence ]
+        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* | len(x) sequence of strings ]
+        labels : None or list
             A sequence of strings providing the labels for each wedge
 
-          *autopct*: [ *None* | format string | format 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*: scalar
+        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*: scalar
+        labeldistance : float
             The radial distance at which the pie labels are drawn
 
-          *shadow*: [ *False* | *True* ]
+        shadow : bool
             Draw a shadow beneath the pie.
 
-          *startangle*: [ *None* | 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* | scalar ]
+        radius : None or float
           The radius of the pie, if *radius* is *None* it will be set to 1.
 
-          *counterclock*: [ *False* | *True* ]
+        counterclock : bool
             Specify fractions direction, clockwise or counterclockwise.
 
-          *wedgeprops*: [ *None* | dict of key value pairs ]
+        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* | dict of key value pairs ]
+        textprops : None or dict
             Dict of arguments to pass to the text objects.
 
-          *center*: [ (0,0) | sequence of 2 scalars ]
-          Center position of the chart.
-
-          *frame*: [ *False* | *True* ]
-            Plot axes frame with the chart.
+        center :  list of float
+          Center position of the chart. Takes value (0,0) or is a sequence
+          of 2 scalars.
 
-          *rotatelabels*: [ *False* | *True* ]
-            Rotate each label to the angle of the corresponding slice.
+        frame : bool
+            Plot axes frame with the chart if true.
 
-        The pie chart will probably look best if the figure and axes are
-        square, or the Axes aspect is equal.  e.g.::
+        rotatelabels : bool
+            Rotate each label to the angle of the corresponding slice if true.
