[proFit-list] creating a third y-axis

What happens if the third axis Z is is a function of X & Y ==> z=f(x,y) in which we can not us superposition. For example z=ln (x^y)?

Delete the plotted data, hide the labels, ticks and axes of all except the 3rd y-axis in this second graph.  Off set it to the right of your 1st graph and send it to the background.   Hide the 3rd axis on the first graph.  Add a title for the third axis.

I have had a few goes at doing this, but so far I never been able to get a y-axis positioned at an x- value greater the maximum x-value or less than the minimum x-value. I could extend the x-axis to beyond its current maximum and position the new y-axis along this new region, but I think that would not look so good. I’m sure there must be a simple way of doing this, but I am not figuring it out from the dialogs or the manual.
