I would like to connect my PieSeries with a tooltip. Cause the datasource is from C++ i generate the PieSeries dynamical this way:

        Connections{
            target: chartData
            onAssignmentPointsRead: //Signal from the C++ object
            {
                chart_assignPoints.removeAllSeries();
                var seriesOut = chart_assignPoints.createSeries(ChartView.SeriesTypePie, "Pos-Points");
                seriesOut.size = 0.96
                seriesOut.holeSize = 0.7
                seriesOut.append("Assignment 1", chartData.getAssignmentPoint(ChartData.POSASSIGN1)); //ChartData is the C++ object
}

Where and how could I add the toolTip? In the Connection? I need the toolTip to show the labeltext + the value in Slices where the space is not enough.

Thanks in advance!
