2D graphic repaint logic

[ralphtan]

I encounter some problem in the LineGraph.java.
LineGraph.java will drawString in the Graph component.It have the predefined value in some other class(PMGraph2.java)
But i failed to pass the new value from ValueInput.java into the LineGraph.java to repaint.
Can anyone pls advice ...URGent
