3D Surface Plot
The 3D surface plot allows to display threedimensional curved surfaces which are estimated from a set of data points. Each data point is defined by three coordinates, x, y, and z. These data points may be (and usually will be) irregularly distributed across the xyplane. DataLab performs an automatic interpolation of the irregular data grid to estimate the 3D surface. This interpolation may be controlled by the type of interpolation (biquadratic regression or weighted Gaussian kernels), the number of neighbors used for the estimation, and a smoothing parameter (in the case of weighted Gaussian kernels).
