How can I mark isotemperature lines on chromaticity diagram with equal Δuv lines?

12 December 2015 1 8K Report

I have found CCT of my samples using formulae. But how to plot isotemperature lines with equal Δuv lines on Chromaticity diagram using origin software to mark that point.

Anders Thorseth

I guess, origin does not come with a "color" module? You probably have to calculate a number of sets of chromaticity points and then plot these sets as simple lines. In the CIE 1976 coordinate system, the lines should be of equal length and perpendicular to the locus making the calculation fairly easy.
