Rotated tick labels

Note

Go to the end to download the full example code.

Rotated tick labels#

Rotating tick labels can be useful when the labels are long and overlap with each other. Adjust the tick properties using 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 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.
