无法在python中使用matplotlib和cartopy绘制轮廓图子图

Question

我试图在分析后将NetCDF文件中的2个图形绘制成子图，我可以单独绘制，但不能作为子图绘制。没有显示错误，但图形显示不正确

import xarray as xr
import matplotlib.pyplot as plt
import cartopy.crs as ccrs
import numpy as np
import cartopy.mpl.ticker as cticker

#%% OLR Import
fname ='/home/SIMS/P1/*.nc'                                              
ds = xr.open_mfdataset(fname)

olr = ds.olr
mea = ds.mean('time')

# OLR daily data import
cname ='/home/SIMS/olrr/OLR.nc'
dc = xr.open_dataset(cname)
colr = dc.olr

# calculating JJAS climatology 
def is_jjas(month):
    return (month >= 6) & (month <= 9)

seasonal_data_olr = colr.sel(time=is_jjas(colr['time.month']))
climatology = seasonal_data_olr.mean('time')
# Anomaly
anomaly_olr=mea-climatology



fig = plt.figure()
ax = plt.axes(projection=ccrs.Mercator(central_longitude=80.0, min_latitude=-10.0, max_latitude=20.0, globe=None, latitude_true_scale=0.0))
plt.subplot(2,1,1)
climatology.plot.contourf(ax=ax,transform=ccrs.PlateCarree(),vmin=0, vmax=245)
plt.subplot(2,1,2)
anomaly_olr.olr.plot.contourf(ax=ax, transform=ccrs.PlateCarree(),cmap="jet", vmin=-30, vmax=30)
plt.show()

我的变量

气候学

xarray.DataArray 'olr' (lat: 15, lon: 73)

异常

xarray.DataArray 'olr' (lat: 15, lon: 73)

它给出了这个没有轮廓的数字

Answer 1

在做了一些修改后，我可以很好地绘制它。我改了几行如下：

plt.figure(figsize=(8, 10))
ax1 = plt.subplot(2,1,1, projection=ccrs.Mercator(central_longitude=80.0, min_latitude=-10.0, max_latitude=20.0, globe=None, latitude_true_scale=0.0))
anomaly_olr.olr.plot.contourf(ax=ax1, transform=ccrs.PlateCarree(),cmap="jet", vmin=-30, vmax=30)

ax2 = plt.subplot(2,1,2, projection=ccrs.Mercator(central_longitude=80.0, min_latitude=-10.0, max_latitude=20.0, globe=None, latitude_true_scale=0.0))
climatology.plot.contourf(ax=ax2,transform=ccrs.PlateCarree(),vmin=0, vmax=245)
plt.show()

无论如何谢谢你
