3D plot

I was hoping to transpose a 3d scatter plot so that the arc shaped data falls flat into the x-y plane. The data, since its a x-section of point cloud spatial data, really is almost entirely in one plane, so I'm hoping to get the best fit in 2D and not in 3D.

Any ideas?


Re: 3D plot

You could use principal components analysis to create 2 orthogonal vectors that define the coordinates of the two dimensional plane and then model in the new coordinate system or use the definitions of those vectors to transform your data
