Hi Jim and others, You should definitely reuse the basemap instance but from your reply it seems like you would also like to reuse the figure instance. The current figure instance is changed when you make plot commands like map.drawcountries(). What I do is to remove the stuff that should not be reused. That is something like this: # If first time create figure from basemap using my function getfigure if fig == None: fig = getfigure(map) # The figure I am plotting on has two axes which I change - an axes with the plot and an axes with a colorbar ax = fig.get_axes()[0] cax = fig.get_axes()[1] # Create plot and save figure cs = map.contourf(lon, lat, data, ax=ax) fig.colorbar(cs, cax=cax, orientation='vertical', extend='both') fig.savefig(filename) # Remove contourf axes ContourSets for c in cs.collections: ax.collections.remove(c) # Remove colorbar axes ContourSets cax.collections = [] Hope it helps.
