A Normal Quantile Plot does not perform a transformation to normal, rather, it provides a visual picture to help determine if a distribution is normal. The plot and the statistical details are all available in the Help screens provided with JMP. The easy way to access the Help for anything being displayed in JMP, is to use the "?" tool from the Tool Bar
and then just move the "?" to the graph or table of interest and click on it, it will display the JMP Help for that object.
Note: at the bottom of the Help screen, there is a link to the Statistical Details.
