Remarks
You can use the LayoutDirection and SimpleDiagram.Dimension properties to change the layout of multiple pie charts in a diagram. The SimpleDiagram.Dimension property specifies how many pie charts can be displayed in one row or column.
| Property Settings | Dimension = 3 | Dimension = 2 |
|---|---|---|
| LayoutDirection = Horizontal |  |
 |
| LayoutDirection = Vertical |  |
 |
Pie charts in an incomplete row or column automatically change their size to occupy all the available space.
The value that you assign to the LayoutDirection property is ignored while the ChartControl.AutoLayout property is enabled. For this reason, you should disable AutoLayout before the LayoutDirection property value is changed.
chartControl1.AutoLayout = false;
((SimpleDiagram)chartControl1.Diagram).Dimension = 3;
((SimpleDiagram)chartControl1.Diagram).LayoutDirection = LayoutDirection.Vertical;
