Rotating Plot

You can now fit either a piecewise-linear surface or a thin-plate smoothing spline to a cloud of three-dimensional data. The surface may be color-coded and color-blended. The color that you place on the surface may represent a fourth variable, thus allowing you to visualize the level sets of a fourth variable as contours along the Z direction in 3-dimensional space. You can also interactively change the resolutions of the rectangular grid for the surface in order to get better quality or performance.
