When the xamTreemap™ control displays hierarchical data, there might be nodes which are not large enough to be seen.
Notice the small nodes.
The ItemMinSize property allows the user to set the minimum size of the nodes. If a node’s width or height is smaller than the ItemMinSize, then the node is rendered as transparent image instead of a UIElement.
In XAML:
<ig:xamTreemap x:Name="Treemap" ItemMinSize="56" >
In Visual Basic:
Treemap.ItemMinSize = 56
In C#:
Treemap.ItemMinSize = 56;
