Contourf does not add cyclic point #1402
Description
Description
For non-cyclic data, contourf does not plot continuous data automatically. When there is no problem with pcolormesh. See example below for contourf:
Data: snc_LImon_IPSL-CM6A-LR_historical_r1i1p1f1_gr_185001.zip
This is pretty inconvenient, to add the cyclic point "by hand" previously to do a plot with from cartopy.util import add_cyclic_point. It would be nice to have an option directly when we plot or to automatically do it when making a contourf.
Code to reproduce
import xarray as xr
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import cartopy.crs as ccrs
from cartopy.mpl.gridliner import LONGITUDE_FORMATTER, LATITUDE_FORMATTER
plt.figure(figsize=(10,4))
ax = plt.axes(projection=ccrs.PlateCarree())
da.plot.contourf(ax=ax, transform=ccrs.PlateCarree())
ax.coastlines()
ax.set_global()
gl = ax.gridlines(crs=ccrs.PlateCarree(), draw_labels=True, linewidth=0.7, color='gray', alpha=0.5, linestyle='--')
gl.xlabels_top = False
gl.ylabels_right = False
gl.xformatter = LONGITUDE_FORMATTER
gl.yformatter = LATITUDE_FORMATTERThanks in advance to consider this. I hope it is not already a topic that was already treated.
