[Wrf-users] How to have a more continuous colourbar with ticks that don't become overloaded?

[Maxime Colin]

Hi all,


I'm trying to get a map with visually smoother colours. I think it would be nice to increase by a large number the levels used in the gsn_csm_contour function. But at the same time, I still want about 10 ticks maximum on the colourbar. Is there any simple way to do this?


Attached is the map I'm working on (1), and the smoother type of map I'd like to produce with NCL (2).


You can find below an extract of my script.


Thank you very much,


Maxime

            gsn_define_colormap(wks,"NCV_blu_red")

            res at tiXAxisString = "x (km)"
            res at tiMainString = "OLR, num_day=" + num_day + ", num_output=" + num_output
            res at gsnMaximize = True
            plot = gsn_csm_contour(wks,olr_big_array(length_single_file*(num_day-1)+num_output,:,:),res)
