Craete a chart with different expression representation

[#1]

Hi,

We need to create a chart like this one:

The problen we need to represent the Imps expression not as a simple line (like the other expressions) but as a line that the area under it is full with color (see above).

How can we accomplish it?

Thanks,

Maybe be sneaky and lay one transparent chart on top of another?

Thanks, it could be some kind of solution, but i still want to be sure there is no better possibility to achaieve this.
