Class PlaceNode1

java.lang.Object
  weka.gui.treevisualizer.PlaceNode1

All Implemented Interfaces:

NodePlace

public class PlaceNode1

extends java.lang.Object

implements NodePlace

This class will place the Nodes of a tree.

It will place these nodes so that they symetrically fill each row. This is simple to calculate but is not visually nice for most trees.
