We do have a new showcase application coming with a bunch of new examples in it, including gauge's. Until that gets published, here's the gauge example source code in case it helps:
public Chart createChart() {
final Chart chart = new Chart()
.setType(Series.Type.GAUGE)
.setAlignTicks(false)
.setPlotBackgroundImage(null)
.setBorderWidth(0)
.setPlotShadow(false)
.setChartTitle(new ChartTitle()
.setText("Speedometer with dual axes")
)
.setPane(new Pane()
.setStartAngle(-150)
.setEndAngle(150)
);
chart.setGaugePlotOptions(new GaugePlotOptions()
.setDataLabels(new DataLabels()
.setEnabled(true)
.setY(30)
.setFormat("{point.y} km/h")
)
.setPivotOptions(
new Pivot()
.setRadius("2%")
)
.setDialOptions(
new Dial()
.setRearLength("0%")
.setBaseWidth(10)
)
);
// Primary axis
chart.getYAxis(0)
.setMin(0)
.setMax(200)
.setTickPosition(Axis.TickPosition.INSIDE)
.setMinorTickPosition(Axis.TickPosition.INSIDE)
.setLineColor("#339")
.setTickColor("#339")
.setMinorTickColor("#339")
.setOffset(-25)
.setLineWidth(2)
.setTickLength(5)
.setMinorTickLength(5)
.setEndOnTick(false)
.setLabels(
new YAxisLabels()
// There is no documented "distance" option for gauge chart axes
.setOption("distance", -20)
)
;
// Secondary axis
chart.getYAxis(1)
.setMin(0)
.setMax(124)
.setTickPosition(Axis.TickPosition.OUTSIDE)
.setMinorTickPosition(Axis.TickPosition.OUTSIDE)
.setLineColor("#933")
.setTickColor("#933")
.setMinorTickColor("#933")
.setOffset(-20)
.setLineWidth(2)
.setTickLength(5)
.setMinorTickLength(5)
.setEndOnTick(false)
.setLabels(
new YAxisLabels()
// There is no documented "distance" option for gauge chart axes
.setOption("distance", 12)
)
;
final Series series = chart.createSeries();
chart.addSeries(series
.setName("Random speed")
.addPoint(80)
);
final Timer tempTimer = new Timer() {
@Override
public void run() {
long inc = Math.round((Random.nextDouble() - .5) * 20);
long cur = series.getPoints()[0].getY().longValue();
series.getPoints()[0]
.update(cur + inc);
}
};
tempTimer.scheduleRepeating(2000);
return chart;
}

@Shawn before asking for a showcase I tried coding to myself, wrt example of Polar charts, but I have the same error when I add the series to the chart:

GWT Highcharts 1.6.0 supports the Gauge chart.
Is it possible have a showcase for this chart type?
Thanks

Resolved.
I forget to add the script tag for "highcharts-more.js" into the HTML file.
@Shawn thank you very much!
