pcolormesh not plotting onto 'ortho' basemap

Hi There,

So I'm really new at this and quite out of my depth.

I was wondering if you could tell me why the following code is just giving me a blank sphere and not one with my pcolormesh information on:

from mpl_toolkits.basemap import Basemap
from netCDF4 import Dataset
import matplotlib.pyplot as plt
import numpy as np

convrain_set = Dataset('proxconvrain30.nc')
lats = convrain_set.variables['latitude'][:]
lons = convrain_set.variables['longitude'][:]
convrain = convrain_set.variables['cvrain'][:]
convrain = np.squeeze(convrain)
convrain_mean = np.mean(convrain,0)

map = Basemap(projection='ortho',lat_0=45,lon_0=-100,resolution='l')

map.drawmeridians(np.arange(0,360,30))
map.drawparallels(np.arange(-90,90,30))

lon,lat = np.meshgrid(lons,lats)

map.pcolormesh(lon,lat,convrain_mean)

plt.show()

I imagine I've just missed something simple and a little silly...

(Sorry if I've pub this question in the wrong place... I figured the people here were the best placed to help...)

All the best,

Neil

首先使用 Basemap、netCDF4、NumPy 和 Matplotlib 重现 issue 中的脚本，然后使用提供的 longitude、latitude 和 convrain_mean 数组以及 ortho 投影检查 Basemap 的 pcolormesh 调用。将绘制结果与经线和纬线进行比较；当降雨数据出现在地球仪上，而不是只显示一个空白球体时，即表示完成。
