How to color code by sample type in a PCA?

Created: Mar 4, 2021 06:37 PM  |  Last Modified: Jun 8, 2023 08:29 PM (1795 views)

I am novice at JMP, and I am making my first PCA that I would like to color code by sample type (treatment) ... but I cannot figure out how. Any advice?

My study compares a variety (15+) of carbon composition metrics of the leaves, litter, and soil of two different plant species in rivers versus creeks -- overall that is 12 sample types, or treatments.

Any help would be greatly appreciated!

I have JMP Pro 12.

Hi,
In the PCA plot, right click on the graph and select "ROW LEGEND", you can then choose the column that will be used to color code the dots on your plot.
Best,
