Parameters: minY the minimum y value (in Java2D coordinate space). height the height available for all labels.

distributeLabels

public void distributeLabels(double minY, double height)
Distributes the labels.

Parameters: minY the minimum y-coordinate in Java2D-space. height the available height (in Java2D units).

sort

public void sort()
Sorts the label records into ascending order by y-value.

spreadEvenly

protected void spreadEvenly(double minY, double height)
Labels are spaced evenly in the available space in an attempt to eliminate the overlaps.

Parameters: minY the minimum y value (in Java2D coordinate space). height the height available for all labels.

toString
