Origin Ver. 2015 and Service Release 1 (Select Help-->About Origin):
Operating System: Windows 8.1
Hello all,
I am a beginner on Origin and also new to this forum. I am currently working with a PCA on a large set of data, and I want to produce a biplot with different colours according to groups, similar to the image shown below (1). This is to show groups in my data. All graphs I produced so far have all data points are in the same colour. I also tried to insert columns with names and change symbol colours with indexing, still nothing worked (2).
Is there any chance anyone could show me how to do this?

Hi,
By default Origin will only search columns in the same worksheet as data columns used in PCA plot for color mapping.
To make the desired mapping column available for symbol or data label color, you only need to copy your mapping columns, CLA, TECHCE,etc, in data sheet to the generated Score Data # worksheet.
Then use the newly added column as colormapping.
Regards!
