By default, the Layout property is exLayoutTTB. Use the Layout property to arrange the nodes from left to right. If the Layout property is exLayoutTTB ( by default ), the parent nodes go from the top to bottom, the child nodes go from left to right. If Layout property is exLayoutLTR, the parent nodes go from the left to right, the child nodes go from top to bottom.

The indent properties work differently based on the Layout property as follows:

• exLayoutTTB ( by default ) - the nodes are arranged from top to the bottom:
  • IndentSiblingX property indicates the horizontal distance between two sibling nodes.
  • IndentSiblingY property indicates the vertical distance between a node and it's child nodes.
  • InflateGroupY property indicates the vertical distance to increase the group of nodes (AddGroup). 

   

• exLayoutLTR - the nodes are arranged from left to the right:
  • IndentSiblingX property indicates the horizontal distance between a node and it's child nodes.
  • IndentSiblingY property indicates the vertical distance between two sibling nodes.
  • InflateGroupX property indicates the horizontal distance to increase the group of nodes (AddGroup).

The following screen shot shows the nodes arrangement when the Layout property is exLayoutLTR:
