Hello, I have Mathematica 4 and have two questions. 1) I have a 3D scatter plot, and I would like to do a least squares fit to the data, and display the R^2 value. Since the graph is 3D, the curve fit should be a surface. I don't think I can do this conveniently, has anyone found a work around for this? 2) Also, it is difficult to visualize the location of the data in the plot, with or without the grids. I once saw another graph (it may have been Igor software?) in which each of the data points were attached to lines that were parallel to the z-axis and stopped at the x-y plane. This is a very nice feature. Is there something equivalent in Mathematica to help improve with being able to visualize the graph? Thanks, Jay
