The base polar transform. This handles projection *theta* and
*r* into Cartesian coordinate space *x* and *y*, but does not
perform the ultimate affine transformation into the correct
position.

� ThetaTicka�
A theta-axis tick.
This subclass of `.XTick` provides angular ticks with some small
modification to their re-positioning such that ticks are rotated based on
tick location. This results in ticks that are correctly perpendicular to
the arc spine.
When 'auto' rotation is enabled, labels are also rotated to be parallel to
the spine. The label padding is also applied here since it's not possible
to use a generic axes transform to produce tick-specific padding.

Set the minimum and maximum theta values.
Can take the following signatures:
- ``set_thetalim(minval, maxval)``: Set the limits in radians.
- ``set_thetalim(thetamin=minval, thetamax=maxval)``: Set the limits
in degrees.
where minval and maxval are the minimum and maximum limits. Values are
wrapped in to the range :math:`[0, 2\pi]` (in radians), so for example
it is possible to do ``set_thetalim(-np.pi / 2, np.pi / 2)`` to have
an axes symmetric around 0. A ValueError is raised if the absolute
angle difference is larger than a full circle.

Set the location of theta's zero.
This simply calls `set_theta_offset` with the correct value in radians.
Parameters
----------
loc : str
May be one of "N", "NW", "W", "SW", "S", "SE", "E", or "NE".
offset : float, default: 0
An offset in degrees to apply from the specified *loc*. **Note:**
this offset is *always* applied counter-clockwise regardless of
the direction setting.

Set the data limits for the radial axis.
Parameters
----------
bottom : float, optional
The bottom limit (default: None, which leaves the bottom
limit unchanged).
The bottom and top ylims may be passed as the tuple
(*bottom*, *top*) as the first positional argument (or as
the *bottom* keyword argument).
top : float, optional
The top limit (default: None, which leaves the top limit
unchanged).
emit : bool, default: True
Whether to notify observers of limit change.
auto : bool or None, default: False
Whether to turn on autoscaling of the y-axis. True turns on,
False turns off, None leaves unchanged.
ymin, ymax : float, optional
These arguments are deprecated and will be removed in a future
version. They are equivalent to *bottom* and *top* respectively,
and it is an error to pass both *ymin* and *bottom* or
*ymax* and *top*.
Returns
-------
bottom, top : (float, float)
The new y-axis limits in data coordinates.

Set the theta gridlines in a polar plot.
Parameters
----------

The angles of the theta gridlines.

The labels to use at each theta gridline. The
`.projections.polar.ThetaFormatter` will be used if None.

Format string used in `matplotlib.ticker.FormatStrFormatter`.
For example '%f'. Note that the angle that is used is in
radians.
Returns
-------

The theta gridlines.
labels : list of `.text.Text`
The tick labels.
Other Parameters

in azimuth while zooming is done along the radial.
