This should work fine as long as you make the figure frame and axes frame invisible. Basically, you need to create the figure background, and the axes background with all the grid lines, tick labels, coastlines, etc, save it, and then for the new figure make sure all the stuff you have saved is turned off. I am not a basemap user, but I know all this stuff is ultimately exposed. Eg for a plain vanilla axes, you would do fig1 = figure(frameon=False) ax1 = fig1.add_subplot(111) fig = figure(frameon=False) ax = fig.add_subplot(111, frameon=false, xticks=[], yticks=[]) fig.canvas.restore_region(background) This will turn off the rendering of both the background rectangle as well as all the ticks and their associated labels, ticklines and gridlines. Perhaps Jeff can advise you vis-a-vis the basemap api what the equivalent is ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
