Hi @ChesterKnurek,
The reason the graph is switching on you after a certain number of X Axis variables has to do with JMP making an inference about the way to combine the scales of the multiple X variables. You'll see in your second graph that you have the switching arrows, which allow you to flip the scale of these independently scaled bins. That's an indication that JMP switched how it's representing the scales of these x variables.
You have those because JMP is guessing, with this many bins and sufficiently different scales, that you want to treat these are parallel independent scales (i.e., as a parallel coordinate plot).
You can confirm this by right clicking the X Axis > Combine Scales, and change "Auto" to "Parallel Independent." Nothing will change -- that's what "Auto" has picked for you with that many X variables.
The fix is easy. Select Parallel Merged. That's what "Auto" will select for you with fewer X variables. I also reversed the scale for the X Axis here to match your target plot.
(Separately, I agree with others that stacking your data and approaching this plot in a more standard way for JMP will probably allow you to do more with the data)
I hope this helps!
