Hi @DJ_Kim ,
I've done a deeper dive on this after some discussions with colleagues - the issue that appears is because you have >30 variables, so the PCA platform is automatically disabling the labelling of variables. This is shown in this help section:
"The loading plot labels variables if the number of variables is 30 or fewer. If there are more than 30 variables, the labels are off by default"
Because this can't be toggled in JMP Live at the moment, you can't activate the labels. A good option to bring to Wish List potentially if you see it as valuable.
Thanks!
Ben
