-        Parameters
-        ----------
-        bottom : float, optional
-            The bottom limit (default: None, which leaves the bottom
-            limit unchanged).
-            The bottom and top ylims may be passed as the tuple
-            (*bottom*, *top*) as the first positional argument (or as
-            the *bottom* keyword argument).
-
-        top : float, optional
-            The top limit (default: None, which leaves the top limit
-            unchanged).
-
-        emit : bool, default: True
-            Whether to notify observers of limit change.
-
-        auto : bool or None, default: False
-            Whether to turn on autoscaling of the y-axis. True turns on,
-            False turns off, None leaves unchanged.
-
-        ymin, ymax : float, optional
-            These arguments are deprecated and will be removed in a future
-            version.  They are equivalent to *bottom* and *top* respectively,
-            and it is an error to pass both *ymin* and *bottom* or
-            *ymax* and *top*.
-
-        Returns
-        -------
-        bottom, top : (float, float)
-            The new y-axis limits in data coordinates.
