OK, I definitely have it updating now. Woo!

I've added some methods to the ChartGenerator class to be able to pre-set
the domain and ranges. In case anyone is interested.

public void setRangeAxisRange(double lower, double upper)
        {
        XYPlot xyplot = (XYPlot)(chart.getPlot());
        xyplot.getRangeAxis().setRange(lower, upper);
        }

public void setDomainAxisRange(double lower, double upper)
        {
        XYPlot xyplot = (XYPlot)(chart.getPlot());
        xyplot.getDomainAxis().setRange(lower, upper);
        }
