What about asking on the GWT Highchart Forum ? Or see if it can be done in pure JS and try to replicate that using GWT ?

i want to use gwt and gwt highcharts in eclipse to visualize data, is there a function on gwt highcharts for using in java, that let to calculate an average value? how can i be calculated the average value (median or mean of that values on xaxis) for this chart for example:
--final Chart chart = new Chart()
.setType(Series.Type.SPLINE)
.setChartTitleText("Wind speed during two days")
.setChartSubtitleText("October 6th and 7th 2009 at two locations in Vik i Sogn, Norway")
.setToolTip(new ToolTip()
.setFormatter(new ToolTipFormatter() {
public String format(ToolTipData toolTipData) {
return DateTimeFormat.getFormat("d. MMMM YYYY HH:00").format(
new Date(toolTipData.getXAsLong())
) + ": " + toolTipData.getYAsDouble() + " m/s";
}
})
)
.setSplinePlotOptions(new SplinePlotOptions()
.setLineWidth(4)
.setHoverStateLineWidth(5)
.setMarker(new Marker()
.setEnabled(false)
.setHoverState(new Marker()
.setEnabled(true)
.setSymbol(Marker.Symbol.CIRCLE)
.setRadius(5)
.setLineWidth(1)
)
)
.setPointInterval(3600000) // one hour
.setPointStart(
DateTimeFormat.getFormat("yyyy-MM-dd").parse("2009-10-06").getTime()
)
);
chart.getXAxis()
.setType(Axis.Type.DATE_TIME);
final YAxis axis = chart.getYAxis();
final Color blueColor = new Color(68, 170, 213, 0.1);
final Color clearColor = new Color(0, 0, 0, 0);
axis.setAxisTitleText("Wind speed (m/s)")
.setMin(0)
.setMinorGridLineWidth(0)
.setGridLineWidth(0)
.setAlternateGridColor(null)
.setPlotBands(
axis.createPlotBand() // Light air
.setFrom(0.3)
.setTo(1.5)
.setColor(blueColor)
.setLabel(new PlotBandLabel()
.setText("Light air")
.setStyle(new Style()
.setColor("#606060")

axis.createPlotBand() // Light breeze
.setFrom(1.5)
.setTo(3.3)
.setColor(clearColor)
.setLabel(new PlotBandLabel()
.setText("Light breeze")
.setStyle(new Style()

chart.addSeries(chart.createSeries()
