I am facing the problem regarding the PCA plot, it keeps crashing (Ubuntu unknown error), or stuck in the processing panels for mins. After you can get in the PCA analysis panel (really by chance), then I can not change the color of the graph.
I have the same question. It is okay to change the shape of groups. However, it does not display when change the color. Have you solved this question?
I am trying it for the whole day, and it does not work at all. I try to change the color and the shape of each group, but the figure does not show up after re-submit. Probably there is something wrong with the new update
Please see my recent post that has a detailed explanation of the same problem.
