How do you calculate the PR Curve in JMP's addin XGBOOST?

I am needing to determine the PR Curve for XGBOOST (addin in JMP Pro), is there a way to ask JMP to output it? Otherwise, would the calculation:

the number of true positives divided by the total number of true positives and false positives suffice in manually calculating the PR Curve?

It does seem to get added to the platform based on (column?) inputs

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
obj = XGBoost(Y(:age), X(:height, :weight), Fit);
