But this won't give you the fancy equation feature. You won't be able to zoom or pan around in the plot and have it automatically update. To do this with "cg" you would need to have some sort of event handler, and then manually update the data or something.
Advantage, new graphics. ;-)

If you want to zoom or pan around, you have to use cgZPlot:
cgZPlot, FINDGEN(101)/100 * 20 - 1
No doubt, you could figure out how to override the event handing there.
:-)
