DPlot

I'm a little bit under the gun so I don't have a lot of time to explore. Can I draw a supply and demand chart, where I just draw the lines for a chart. Presently I am interested in using this as a visual aid rather then a statistics tool. I used it in a past math class, just purchased this latest version and am over 50 with little memory.

Rick,
There's no way to 'draw lines' to create a graph, if you mean point-and-clicking. You can easily enter the X,Y values for your graph with Edit>Edit Data, though.
