# Create a longitude grid

Parameters
----------
data : ~pyarts3.arts.LonGrid
A sorted grid of longitude values [-180, 180)
fig : ~matplotlib.figure.Figure, optional
The matplotlib figure to draw on. Defaults to None for new figure.
ax : ~matplotlib.axes.Axes | list[~matplotlib.axes.Axes] | ~numpy.ndarray[~matplotlib.axes.Axes] | None, optional
The matplotlib axes to draw on. Defaults to None for new axes.
polar : bool, optional
If True, use polar plot. Defaults to False.
**kwargs : keyword arguments
Additional keyword arguments to pass to the plotting functions.
Returns
-------
fig :
As input if input. Otherwise the created Figure.
ax :
As input if input. Otherwise the created Axes.
