Thanks a lot for the quick help! How to project the scatter plot with the diagonal line to the three planes with scatterplot3d? I could not find such an example demonstrating that in the vignette.
I'm puzzled. If you have (x1, y1, z1) and (x2, y2, z2) as starting and ending points, Deducing the three projected segments , i.e. the starting and ending points of the projections on the xy, xz and yz planes (z = 0, y=0, and x= 0 respectively) would seem to be trivial. So maybe I just don't understand. What part is offering difficulty? Please show your code so far.
