Graphing 2 axis labels on 1 axis?

I've been messing around with the different graphing features for Igor and I'm trying to figure out if there's a way to place to sets of axis labels (ticks and all) on 1 axis. I've looked through the old posts but these seem to focus only on creating axis labels, or on switching between the left/right or top/bottom axis. I've attached an example plot below, but what I want to know is if there's a way to "move" the top axis (MeVee) so that it is shown on the bottom axis. I'm really not a fan of using the top axis, but if it's between that or creating two separate graphs I'd like to know. FittingTest.jpeg
To get an axis you can position anywhere, use a "free" axis. To plot that trace against a bottom free axis, when you create the graph or append the trace to the graph, pop up the horizontal axis menu that's below the list of X waves and select New. That will bring up a dialog where you set the name of the new free axis and select either Top or bottom.

The new axis will be positioned strangely. I recommend double-clicking the axis to bring up the Modify Axis dialog. In the Axis tab, in the Free Axis Position area in the bottom left corner of the Axis tab, select Fraction of Plot Area. Zero positions the axis where you expect, and other values offset it, as you may need to avoid colliding with the other axis.
