+        ----------
+        layout : {'constrained', 'compressed', 'tight', 'none', `.LayoutEngine`, None}
+
+            - 'constrained' will use `~.ConstrainedLayoutEngine`
+            - 'compressed' will also use `~.ConstrainedLayoutEngine`, but with
+              a correction that attempts to make a good layout for fixed-aspect
+              ratio Axes.
+            - 'tight' uses `~.TightLayoutEngine`
+            - 'none' removes layout engine.
+
+            If a `.LayoutEngine` instance, that instance will be used.
+
+            If `None`, the behavior is controlled by :rc:`figure.autolayout`
+            (which if `True` behaves as if 'tight' was passed) and
+            :rc:`figure.constrained_layout.use` (which if `True` behaves as if
+            'constrained' was passed).  If both are `True`,
+            :rc:`figure.autolayout` takes priority.
+
+            Users and libraries can define their own layout engines and pass
+            the instance directly as well.
+
+        **kwargs
+            The keyword arguments are passed to the layout engine to set things
+            like padding and margin sizes.  Only used if *layout* is a string.
