fill areas between two curves

Hi all,

I've got a problem with programming reports with diadem and I don't know how to solve the problem.

Current situation:

I plot 2 lines in a diagram (value table as channels). Now I want to fill the area between these lines. To give a better decription I added a picture in the attachments.

How can I program this with diadem script ?

It would be nice, if somebody could help with this problem.

Thanks a lot.

Cheers EmBee
