[ncl-talk] using loop to get overlay plots into a panel

Instead  of using the gsn_csm_contour() function, try using one of the gsn_csm_contour_map() functions. The generic gsn_csm_contour() does not assume that the data are spatial, so will not include lat/lon gridlines.

As well as the generic contour map function there are several higher level functions  that map onto specific map projections. There is also a gsn_csm_contour_map_overlay() function that will perform your overlay in a single step.

Note that if you don’t use the gsn_csm_contour_map_overlay()  function, then ONLY use the contour map function for the base plot (i.e. plotA)

All the contour mapping functions, including overlays, are in the help pages.

Subject: [ncl-talk] using loop to get overlay plots into a panel

Hello ncl-talk,

I drew a trend plot overlaid with a significance plot and then used a loop to combine this type of plot from six models. However, every plot in that panel does not show latitude and longitude tick marks as well as the trend of my variable. It looks like:

Thank you very much!
