Detailed Description

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.

)

const

Returns the delta value of the X-axis.

The delta is the interval between subsequent values on the axis.

double Wt::Chart::WEquidistantGridData::deltaY

(

)

const

Returns the delta value of the Y-axis.

The delta is the interval between subsequent values on the axis.
