===================
Rotated tick labels
===================

Rotating tick labels can be useful when the labels are long and overlap with each other.
Adjust the tick properties using `~.Axes.tick_params`: Set the angle in degrees via
the *rotation* parameter. Set the *rotation_mode* parameter to "xtick" / "ytick" to
make the text point towards the tick, see also `~.Text.set_rotation_mode`.

Note: We use ``layout="constrained"`` to make sure there is enough space for the tick
labels so that they are not cut off.
