Data Organization

Data in a chart is organized into chart groups. In 3D Chart, a chart group is represented by a ChartGroup object. At present, only one chart group can be stored in a chart group collection.

Within a chart group, the three-dimensional data to be displayed is assumed to come either from a gridded surface, or from one or more series of points. This data is represented by the ElevationData property, which is a Chart3DData object. The data displayed can be in one of three formats:

·      Regularly-gridded data, in which the X- and Y-gridlines are evenly spaced

·      Irregularly-gridded data, in which the X- and Y-gridlines are not evenly spaced.

·      Point data, in which the X, Y and Z coordinates can be specified without restrictions.

To set the data format, set the Layout property to the appropriate data layout constant.
