Data Layout in GridDataSeries
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.
