         A list of `.LineCollection` (empty if no lines were drawn).
     dividers : `.LineCollection`
         A LineCollection (empty if *drawedges* is ``False``).
-
-    Parameters
-    ----------
-    ax : `~matplotlib.axes.Axes`
-        The `~.axes.Axes` instance in which the colorbar is drawn.
-
-    mappable : `.ScalarMappable`
-        The mappable whose colormap and norm will be used.
-
-        To show the colors versus index instead of on a 0-1 scale, set the
-        mappable's norm to ``colors.NoNorm()``.
-
-    alpha : float
-        The colorbar transparency between 0 (transparent) and 1 (opaque).
-
-    location : None or {'left', 'right', 'top', 'bottom'}
-        Set the colorbar's *orientation* and *ticklocation*. Colorbars on
-        the left and right are vertical, colorbars at the top and bottom
-        are horizontal. The *ticklocation* is the same as *location*, so if
-        *location* is 'top', the ticks are on the top. *orientation* and/or
-        *ticklocation* can be provided as well and overrides the value set by
-        *location*, but there will be an error for incompatible combinations.

-    Other Parameters
-    ----------------
-    cmap : `~matplotlib.colors.Colormap`, default: :rc:`image.cmap`
-        The colormap to use.  This parameter is ignored, unless *mappable* is
-        None.
-
-    norm : `~matplotlib.colors.Normalize`
-        The normalization to use.  This parameter is ignored, unless *mappable*
-        is None.
-
-    orientation : None or {'vertical', 'horizontal'}
-        If None, use the value determined by *location*. If both
-        *orientation* and *location* are None then defaults to 'vertical'.
-
-    ticklocation : {'auto', 'left', 'right', 'top', 'bottom'}
-        The location of the colorbar ticks. The *ticklocation* must match
-        *orientation*. For example, a horizontal colorbar can only have ticks
-        at the top or the bottom. If 'auto', the ticks will be the same as
-        *location*, so a colorbar to the left will have ticks to the left. If
-        *location* is None, the ticks will be at the bottom for a horizontal
-        colorbar and at the right for a vertical.
