pcolormesh not plotting onto 'ortho' basemap

Nobody has claimed this yet.

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

Start by reproducing the script in the issue with Basemap, netCDF4, NumPy, and Matplotlib, then inspect the Basemap `pcolormesh` call using the supplied longitude, latitude, and `convrain_mean` arrays with the `ortho` projection. Compare the plotted result with the meridians and parallels; done means the rainfall data appears on the globe rather than showing only a blank sphere.
