There's more than one way to do this. Simple approach: Define three CDEFs, for instance R,Y and G. R is your current CDEF. Y is the same as R however with a MAXimum of 95; G has a maximum of 80% Now plot, in this order, an AREA for R,Y and G. The CDEF for Y could be: CDEF:Y=R,95,GT,95,R,IF This is: if (R>95) return 95 else return R A slightly better way would be to use CDEF and STACK, this means calculating the appropriate values for Y and R (which should be NaN in case the percentage isn't high enough). STACK Y on top of AREA G and STACK R on top of STACK Y. This has a disadvantage of the legend being in the wrong order would you decide to use a legend.
