Any Ideas of how to create Supply/Demand Graphs???

[FunkM4st4Fl3tch]

I wanted to add some graphics of the changes in supply/demand in oil and was wondering if anyone has done it before. I can't seem to find any official SAS procedures for creating such graphs. The only thing I can really come up with is using a line or series chart and plotting two opposite signed number sets... Any ideas would be greatly appreciated! Thank You!

Yes, supply/demand graphs are just simple series lines.

Why "two opposite signed number sets" ?

Surely you only have positive numbers to plot.
