matplotlib-users Mailing List for matplotlib

Hi all! I'm a bit confused now, since I've never had any problems with bluemarble. The problems have always been in me and how I handle the data, and it probably is like that also this time... But the problem is that bluemarble won't show up, the data seems to plot just fine and so do for example drawcoastlines and drawcountries. Where should I dig into?

import matplotlib.pyplot as plt
from mpl_toolkits.basemap import Basemap
from scipy.io.netcdf import netcdf_file as Dataset
import numpy as np
import pylab
import os

months = [3,45]

for month in months:

        SIT = Dataset('SIT.nc','r')
        
        lons = SIT.variables['lon'][:,:]
        lats = SIT.variables['lat'][:,:]

        masked_SIT = np.ma.masked_where(np.isnan(SIT.variables['sea_ice_thickness'][month,:,:] ), SIT.variables['sea_ice_thickness'][month,:,:] )
        
        m = Basemap(width=5400000*2,height=5400000*2,resolution='l',projection='laea',lat_0=90,lon_0=0)


        fig = plt.figure()
        m.pcolormesh(lons, lats, masked_SIT, latlon = True, vmin=0, vmax=5)
        m.bluemarble(scale=0.5)
        m.drawcoastlines()
        m.drawcountries()
        #m.fillcontinents(color='white')
        cbar = plt.colorbar()
        cbar.cmap.set_over('#ff0066')
        cbar.set_label('SIT [m]', fontsize='x-large')
        plt.title('Sea Ice Thickness %s' % (title), fontsize='x-large')

plt.show()
