You could prototype that easily with RRGrapher: http://net.doit.wisc.edu/~plonka/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.)
