I found a way to add a legend box:

load Legend.dx, map   #with Legend.dx as an empty file
zoom PDB_ID           #to view our structure again
ramp_new legend, map, [1.0,5.0,9.0], color=3D['C1',[1.0,1.0,1.0],'C9']
                       #legend is the object name for the names panel
                       #map is the fake map
                       #[1.0,5.0,9.0] is the legend range with
                       #   [min,medium,max] values
                       #color C1 is the min color, and C9 the max color
cmd.delete("map")     #delete the map object

I hope this will help someone.
