How to add lines to an existing 3D scatter plot? (drop lines)

I want to draw drop lines to coordinate plane in a 3D scatter plot to represent the locations of plots but have no idea how to achieve it. I think an alternitve might be to add lines to the scatter plot but have not found how to do that. I was able to create a 3D scatter plot and a line plot seperately but I want to draw them in the same 3D chart. So please help me drawing drop lines for each scatter plot or adding lines to the existing 3D scatter plot. Thanks!

Hi @noverain Welcome to the forums.

What exactly are drop lines?

Is maybe a surface plot with contours similar to what you are trying to do?
