Data Layout in GridDataSeries

In This Topic

Data in Chart3D for WPF and Silverlight is defined in the GridDataSeries class. It provides the following properties related to data:

Property	Description
ZData	Gets or sets two-dimensional array of values on the grid.
Start	Gets or sets the start point of data.
Step	Gets or sets the step of grid data.
ContourData	Gets or sets two-dimensional array of contour data (4-dimensional chart).

The first index of the 2D array in the ZData/ ContourData properties corresponds to the X and the second index corresponds to the Y. The layout for ZData is shown in the following table.

	Start.X	Start.X + Step.X	Start.X + 2*Step.X
Start.Y	ZData[0,0]	ZData[1,0]	ZData[2,0]
Start.Y + Step.Y	ZData[0,1]	ZData[1,1]	ZData[2,1]
Start.Y + 2*Step.Y	ZData[0,2]	ZData[1,2]	ZData[2,2]

The element of the array ZData[0,0] corresponds to the point (Start.X, Start.Y), ZData[1,0] is the z-value at (Start.X+Step.X, Start.Y), and so on.
