3D散点中的标记点

Question

I have a series of highly-dimensional points. When plotting them in 2D, I can highlight clusters in different colors/markers using:

gscatter(new_data(1,:),new_data(2,:),trainlabels,[],'<x+*sdv^o>ph.')

I would like to do the same with a 3D scatter, but understand that a gscatter3 function doesn't exist and scatter3 doesn't allow me to specify a label set...

Any thoughts?

Answer 1

You can use the command text (x,y,z,str) to label your points in 3D.

scatter3(pointList(1,:),pointList(2,:), pointList(2,:));
text(pointList(1,:),pointList(2,:), pointList(2,:), trainlabels[]);
