Dot size in PCA plots

Dear MA guys
Your software is super cool, and I’m using it a lot. I have a (naive?) question. How do you increase the dot size in the PCA plots? I can control colors, format (dots, crosses, squares…) but I can’t find the way to simply enlarge these dots in the plot. Make them simply bigger for a better reading in publications. Can you help?
thanks!
Andrea

Still no replies? Any help from anybody? thanks
