How do I plot multiple X variables on a plot?

With the new Variable Selection dialog in v4.5, the process for creating Double X and Double XY plots has changed. This would also be used to plot multiple X-Y pairs on the same plot.

1. Choose your plot type.
2. Select your first set of X and Y variables.
3. Click Add to create a new plot group in the dialog.
4. Select your next set of X and Y variables.
5. You can either click Plot if you are done, or click Add and continue adding X-Y pairs until you are ready to plot.
