Error creating Gauge chart

[GoogleCodeExporter]

Here is my code, which is -- for the most part -- a cut and paste of your 
example code for creating and displaying a Gauge chart:

public class SplashPanel extends SimpleLayoutPanel {

    private Gauge chart;

    public SplashPanel() {

    ChartLoader chartLoader = new ChartLoader(ChartPackage.CORECHART);
    chartLoader.loadApi(new Runnable() {
        @Override
        public void run() {
        Widget chart = createChart();
        setWidget(chart);
        drawChart();
        }
     });

    }

    private Widget createChart() {
    if (null == chart)
        chart = new Gauge();

    return chart;
    }

    private void drawChart() {
    // Prepare the data
    DataTable dataTable = DataTable.create();
    dataTable.addColumn(ColumnType.STRING, "Label");
    dataTable.addColumn(ColumnType.NUMBER, "Value");
    dataTable.addRows(3);
    dataTable.setValue(0, 0, "Memory");
    dataTable.setValue(0, 1, 80);
    dataTable.setValue(1, 0, "CPU");
    dataTable.setValue(1, 1, 55);
    dataTable.setValue(2, 0, "Network");
    dataTable.setValue(2, 1, 68);

    // Set options
    GaugeOptions options = GaugeOptions.create();
    options.setGreenFrom(0);
    options.setGreenTo(40);
    options.setYellowFrom(40);
    options.setYellowTo(80);
    options.setRedFrom(80);
    options.setRedTo(100);

    // Draw the chart
    chart.draw(dataTable, options);
    }

Running this code produces the following Exception:

You must change the chart package to ChartPackage.GAUGE
Let me know if it's working. Thank you.

Yes, that did the trick. That is one piece that is not include in your 
examples. Now that I know to look for it, all is good.

Thanks,
Joel
