Smoothing Data

The Smooth method passes a center-weighted averaging function over the chart grid, resulting in a smoother-looking dataset. For example:

Chart3D1.ChartGroups(1).ElevationData.Smooth 0.7

The argument specifies the center weight, and must be between 0 and 1. This method is a nine-point filter using all points adjacent to the center. Each new value is a weighted average of the original value and its surrounding points. The weights of the surrounding points are computed based on the value of the center weight and its distance from the center point.
