Simple Supply And Demand Graph

Maybe the title shouldn't be simple or I am missing something starring me in the face.

I am trying to make a supply and demand graph, with the following table,

wage supply demand
45,000 200,000 325,000
40,000 220,000 310,000
35,000 250,000 300,000
30,000 290,000 290,000
25,000 310,000 275,000
20,000 320,000 250,000

I can make either a supply or a demand graph without problems, however no matter where I place the vaules, ie wage first, demand, then supply or demand, wage, supply, the graph will not work or look right. The wage must be on the left had side so that the graph complies with standard Supply and Demand. I also need to be abble to make another graph showing what happens with a wage cap.

I can do it on graph paper, put I can not find a way to do it using Office 2007 Word and inserting a graph option and using Excel.
