Allow using true scales of X and Y data in contour triangulation

ORG-12492

In Origin 2016 SR0, Origin has implemented the contour triangulation algorithm to be based on raw X and Y data instead of normalized X and Y data as used in old treatment. To revert to old behavior, you can run the command below in Script Window or Command Window and refresh to see:

page.triangulationnormalizedata=1;

In Origin 2016 SR3, there is GUI access to revert.
