Hello dear GrADS users, Is it possible to thick a selected contour isoline? Let's say I want to "set cthick 6" the 0ºC contour isoline from a 2m temperature variable plot. I have seen it in a few GrADS maps on the web. Also, is there any workaround to show contour labels using 'mproj nps' and setting coordinates with 'mpvals'? Any help appreciated. Cheers, Fil
