real-time chart with dates on x-axis

[User (Legacy)]

Hi,

I'm having trouble creating a real-time chart with DateTime's on the X-axis. 

I'm using the RealTime.zip sample program from your download site and trying 

to modify it so that every time the Timer goes off, a new point is added to 

the chart, with the point's y-value being the random number and x-value 

being the current time.  Below is the AddPoint() method with my changes. 

I'm getting an "Index out of bounds" error when running the program.   Am I 

missing something?  Do you have a sample program that does a similiar thing?

thanks,

Heath

private void AddPoint()

{

        // Switch real-time styles once buffer is full

        if (nOffset == BufferSize)

        {

                chart1.RealTimeSettings.Style = 

SoftwareFX.ChartFX.RealTimeStyle.NoWaitArrow;

                chart1.Refresh();

        }

        //Set Communication Channel styles

        //These COD values instruct Chart FX about the Realtime settings

        //the chart, values and legend.

        SoftwareFX.ChartFX.COD nCOD;

        nCOD = SoftwareFX.ChartFX.COD.Values | COD.XValues | 

SoftwareFX.ChartFX.COD.RealTime;

        nCOD = nCOD | SoftwareFX.ChartFX.COD.ScrollLegend;

        //Add a point for each sereis to the right of the chart

        //Using the legend property, set the legend values

        System.Random r;

        r=new System.Random();

        DateTime dt = DateTime.Now;

        chart1.OpenData(COD.Values | COD.AddPoints, 1, 1);

        chart1.OpenData(COD.XValues | COD.AddPoints, 1, 1);

        chart1.Value[0, 0] = -50 + (r.NextDouble() * 100);

        chart1.XValue[0, 0] = dt.ToOADate();

        chart1.CloseData(nCOD);

        nOffset = nOffset + 1;

}
