As always, Jim's (@txnelson) solution is a good one.
I just wanted to point out a little feature that a lot of JMP users don't know exists. Here's the JMP17 help, and should work in JMP15:
In Platform Column Transformation
Instead of analyzing the column directly, make a 100*column transform and analyze that.
Once I learned about this, I couldn't stop using it! Teaching this to other users always elicits the 'OMG, I didn't know you could do that!' response.
