You could prototype that easily with RRGrapher:
To plot below the line you just use an RPN expression multiplying the
desired quantity by -1.
Whether in the positive or negative direction, just stack the values
on top of each other.
For graphs like this, first put all the positive ones (the one nearest
the horizontal axis is AREA, then the rest STACK), and then all the
negative ones (same: AREA, then the rest STACKed). (i.e. don't alternate
the positive and negative when you order them on the command line.)
