Hi, I got the same problem as you. The solution is creating pathpatch
everytime before add_patch
. For example,
from matplotlib.path import Path
from matplotlib.patches import PathPatch
import cartopy.crs as ccrs
import proplot as pplt
fig, axs = pplt.subplots(ncols=3,proj='cyl')
codes = [Path.MOVETO] + [Path.LINETO]*3 + [Path.CLOSEPOLY]
vertices = [(210,-5), (210,5), (270,5), (270,-5), (0, 0)]
path = Path(vertices, codes)
pathpatch = PathPatch(path, facecolor='none', edgecolor='k',lw=1.5,label='Nino3',transform = ccrs.PlateCarree(),alpha = 0.6)
axs[0].add_patch(pathpatch)
pathpatch = PathPatch(path, facecolor='none', edgecolor='k',lw=1.5,label='Nino3',transform = ccrs.PlateCarree(),alpha = 0.6)
axs[1].add_patch(pathpatch)
pathpatch = PathPatch(path, facecolor='none', edgecolor='k',lw=1.5,label='Nino3',transform = ccrs.PlateCarree(),alpha = 0.6)
axs[2].add_patch(pathpatch)

Thanks a lot! I will try it later!
I cant answer why "Can not add patch in every axes".
BUT, maybe I can give you a solution. Actually, you can use ax.plot() to draw area box (plot line).
For example:
ax1.plot([210, 270, 270, 210, 210], [-5, -5, 5, 5, -5], c='r', linestyle='-')

This is a matplotlib limitation -- artists have to be duplicated when adding to multiple axes. I think copying the artist before adding to other axes with copy.copy(pathpatch)
(and adding import copy
to your imports) would also work.
Description
I try to draw the Nino3 area in every axes, BUT here it is the Error:"ValueError: Can not reset the axes. You are probably trying to re-use an artist in more than one Axes which is not supported". The nino3 area is only drawn on the first axs. so How can i fix this? Thanks a lot.
Here is the code for add patch:
Proplot version
0.9.5.post332
