What you describe sounds very much like what I do with Liam Gumley's IMDISP
procedure. You may control all of the behaviors you now control with the
SHADE_SURF commands. Soemthing like the following:
IMDISP, merged, Out_Pos = Pos
(if you need to check for NANs then switch in BYTSCL(merged,/NAN) for merged
PLOT, lonbins,latbins, Position = Pos, /NoErase
You might need to fiddle with the plot command keywords to get the axes to fit
you data range.
Look for Liam's procedure at http://cimss.ssec.wisc.edu/~gumley
