I'm working with ScatterLine graph.

I've tried your sample and it really working well.

After this I started to play with it. I removed all hard-coded datapoints and start to add them pragmatically.

I found out the problem - exception occures when series has no datapoints.

This looks like Infragistics bug.

Thanks for the additional info. We tracked this issue in our system, so this should be fixed in next hotfix release.

Hi,

   I used ScatterLine Chart to draw chart, but want to change my XAxis Label from 1~30 to A~Z? Can I do this?

    I have tried to set label in every datapoint, but the picture is still only show 1~30. How can I do?

this is my Code

        private void funGenerator()
        {

            Series ScatterLineSeries = new Series();
            ScatterLineSeries.ChartType = Infragistics.Windows.Chart.ChartType.ScatterLine;                 
            xamChart1.Series.Add(ScatterLineSeries);
            Infragistics.Windows.Chart.DataPoint pP;

            for (i = 0; i < datasize; i++)
            {
                pP = new Infragistics.Windows.Chart.DataPoint();
                pP.ChartParameters.Add(ChartParameterType.ValueX, i);

                //Set every datapoint's label
                pP.Label = AxisXLabel[i];

                pP.ChartParameters.Add(ChartParameterType.ValueY, i*i);

                ScatterLineSeries.DataPoints.Add(pP);
            }
 }

I think for your case you can use Line chart instead of ScatterLine. With line chart you can simply use:

pP.Label = AxisXLabel[i];

pP.Value = i * i;
