^^^^^^^^^^^^^^^^^^^

You really meant

xrange = !x.crange*3.281

didn't you?!!!!!

Thanks for the dash of cold water! Late Friday evening and a hurry
to get out did result in a moronic example!

I picked a linear relationship (in PV-Wave the example of plotting
temperature in F and C is given :-(' ), but what is the relationship
is not linear? For example, velocity and power so that the upper
axis is the square of the lower one? Is there a nifty way to do
that?
