TreeMapSliceAndDiceLayoutAlgorithm Class

A class representing the Slice and Dice layout algorithm.

Namespace: DevExpress.XtraTreeMap

Assembly: DevExpress.XtraTreeMap.v18.1.dll

Declaration

C#

public class TreeMapSliceAndDiceLayoutAlgorithm :
    TreeMapLayoutAlgorithmBase

VB.NET

Public Class TreeMapSliceAndDiceLayoutAlgorithm
    Inherits TreeMapLayoutAlgorithmBase

Remarks

This algorithm calculates the layout using the following principle. For each tree map level, the layout direction is selected depending on the width/height ratio (for TreeMapSliceAndDiceLayoutAlgorithm.LayoutMode = TreeMapSliceAndDiceLayoutMode.Auto), and for all children items at a given level, the display area is divided amongst the children, where each child item obtains a slice proportional to its value.

The following image demonstrates the country area tree map with a layout calculated using this algorithm.
