Method tight_layout

lib/matplotlib/figure.py:3633–3671

Adjust the padding between and around subplots. To exclude an artist on the Axes from the bounding box calculation that determines the subplot parameters (i.e. legend, or annotation), set ``a.set_in_layout(False)`` for that artist. Parameters ------

(self, *, pad=1.08, h_pad=None, w_pad=None, rect=None)

        return None if event is None else event.name == "key_press_event"

        Adjust the padding between and around subplots.

        To exclude an artist on the Axes from the bounding box calculation
        that determines the subplot parameters (i.e. legend, or annotation),
        set ``a.set_in_layout(False)`` for that artist.

        Parameters
        ----------
        pad : float, default: 1.08
            Padding between the figure edge and the edges of subplots,
            as a fraction of the font size.
        h_pad, w_pad : float, default: *pad*
            Padding (height/width) between edges of adjacent subplots,
            as a fraction of the font size.
        rect : tuple (left, bottom, right, top), default: (0, 0, 1, 1)
            A rectangle in normalized figure coordinates into which the whole
            subplots area (including labels) will fit.
