Dear Mr or Mrs, 

I am working on a netcdf file based on a Lambert Conformal grid. The data (let's name it RR) has lat/lon coordinates. 
I drew it on a map using 
gsn_csm_contour_map(wks,RR(:,:),opts_RR 
and 
optsRR at cnFillMode = "CellFill" (or "RasterFill" ) 
It works perfectly. 

I am now willing to overlay the data values of RR on each grid point, similar to the graph plotted for example [ http://www.ncl.ucar.edu/Applications/Scripts/text_15.ncl | text_15.ncl ] (http://www.ncl.ucar.edu/Applications/text.shtml) 
However, example text_15.ncl refers to data on an (x,y) grid. 

How do we proceed for a lat/lon grid? 
Perhaps use "gsn_coordinates" like in datagrid_6.ncl example (http://www.ncl.ucar.edu/Applications/datagrid.shtml#ex6) but ask for text (= the value of RR at each grid point) instead of markers? 

Thanks for your help, 
Marie-Dominique LEROUX
