PCA - how to find component scores (X,Y coordinates) for each point on plot?

I'm using JMP 13.0, on a Mac to run Princple Component Analysis (PCA) on environmental data.
It's working fine, however I can't seem to find any option to display the X,Y coordinates (PCA scores) for each point on the plot. My plot contains ~50 data points, from several different treatment groups. I'm hoping to calculate a mean value and standard deviation, for PC1 and PC2, for each treatment group, so I can create a new figure displaying average differences between treatment groups along the PC axes.
I think I've tried every drop-down display option for PCA and I cannot find these values anywhere. I've seen plenty of data displayed this way, so it seems like it should be an option in JMP. I also know that R can generate this report.
Can anyone tell me where I can find this information? Thanks.
