Detailed Description

Class representing grid-based data for a 3D chart.

General information can be found at WAbstractDataSeries3D. The model for this dataseries is structured as a table. One of the columns (by default index 0) contains the x-axis values, one of the rows (by default index 0) contains the y-axis values. All other values in the table contain the z-value corresponding to the x- and y-values with the same column- and row-index.
