GaugePanel

public GaugePanel(Gauge g,

public void initGaugePanel()

Initialize the graphics component. In particular, populate the list of "PNodes" (the graphics objects shown on screen).

updateGauge

public void updateGauge()

Update the gauge. Assumes the low-d datapoints (which are what the gauge shows) have been changed. This method is called by the gauge thread

resetGauge

public void resetGauge()

Reset the gauge, removing all PNodes and references to datapoints

addNode

public void addNode(edu.umd.cs.piccolo.PNode theNode)
