Applying theta transforms in ``PolarTransform``
2+
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3+
Applying theta transforms in `~matplotlib.projections.polar.PolarTransform`
4+
is deprecated. This is currently the default behaviour, so to prevent
5+
a warning, manually pass ``_apply_theta_transforms=False``, and
6+
apply any theta shift before passing points to this transform.
