* \brief Class representing grid-based data for on a 3D chart.
*
* General information can be found at WAbstractDataSeries3D. The model for
* this dataseries does not contain an x- and y-axis. Instead the class
* derives the x- and y-values from the minimum and delta provided in the
* constructor. The size of the model determines the size of the grid. The
* model itself is structured as a table, where every value represents the
* z-value of a data-point. The corresponding x- and y-values are calculated
* by adding delta times the row/column-index to the axis-minimum.
