pcolormesh no longer wraps around #1997
Description
Description
pcolormesh no longer draws the "other half" of gridpoints that have their center at the edge of the maps - see the example and figure. This may very well be an 'indended' consequence of #1646 but I thought I report it anyway.
This used to work in older versions of cartopy/ matplotlib (e.g. cartopy=0.19 and matplotlib=3.4)
Code to reproduce
import cartopy.crs as ccrs
import matplotlib.pyplot as plt
import numpy as np
lon = np.arange(-180, 151, 30)
lat = np.arange(75, -76, -30)
LON, LAT = np.meshgrid(lon, lat)
lon_edges = np.arange(-195, 181, 30)
lat_edges = np.arange(90, -91, -30)
data = np.ones(shape=lat.shape + lon.shape)
f, axs = plt.subplots(1, 2, subplot_kw=dict(projection=ccrs.PlateCarree()))
f.subplots_adjust(wspace=0.05)
# 1 - using edges
ax = axs[0]
ax.pcolormesh(
lon_edges,
lat_edges,
data,
transform=ccrs.PlateCarree(),
cmap="Reds",
ec="0.3",
lw=0.5,
)
ax.set_title("using edges")
# 2 - using centers
ax = axs[1]
ax.pcolormesh(
lon,
lat,
data,
transform=ccrs.PlateCarree(),
cmap="Reds",
ec="0.3",
lw=0.5,
)
ax.set_title("using centers")
for ax in axs:
ax.plot(LON.flatten(), LAT.flatten(), "o", ms=1)
ax.coastlines()
ax.set_global()
