matplotlib.axis.Axis.get_tightbbox

Axis.get_tightbbox(renderer=None, *, for_layout_only=False)

Return a bounding box that encloses the axis. It only accounts tick labels, axis label, and offsetText.

If for_layout_only is True, then the width of the label (if this is an x-axis) or the height of the label (if this is a y-axis) is collapsed to near zero. This allows tight/constrained_layout to ignore too-long labels when doing their layout.
