For instance, for the LayoutDirection.TopLeftToBottomRight value, the largest tree map item will be arranged at the top left corner and the smallest item will be placed at the bottom right corner.
Example
To customize the layout algorithm, do the following.
| MainWindow.xaml |
<dxtm:TreeMapControl x:Name="treeMap"
LayoutAlgorithm="{Binding ElementName=lbLayoutAlgorithm, Path=SelectedValue}">
<!-- endregion #LayoutAlgorithm-->
<dxtm:TreeMapControl.Colorizer>
