I am working on a scatter3 plot to visualize PCA data. However, my current plot has 2D markers (circles) for each data point. Instead, I'd like to use a 3D marker (sphere) for each data point. Is that possible? I don't see a sphere option as marker type in scatter3 plot info, so I would imagine I have to do some programming to make this happen. My attempts so far have failed. Any suggestions?

You may create small balls using a "sphere" as follows :

You may also use "scatter3" to generate 3D markers using the "filled" option :
