Create a legend layer and add your legend figure to it.
Then let the legend figure listen for viewport changes and move itself 
accordingly.

            Viewport viewPort = 
((FigureCanvas)graphicalViewer.getControl()).getViewport();
            viewPort.addPropertyChangeListener(new PropertyChangeListener() 
{
        public void propertyChange(PropertyChangeEvent evt)
        {
            if(evt.getPropertyName().equals(Viewport.PROPERTY_VIEW_LOCATION)) 
{
                //Do your thing here
            }
        }
    });
