Hi everyone.

In my app has myArray[x,5]. This myArray is populate every minute. I need add 5 Splines on the chart; one for each y in myArray. Put screenshot for viewing.
Although the values are differents, plot only this single line.
C#, VS2010 Ultimate, WinForms, not WPF.
All help is welcome, thanks in advance, ocaccy

Ok guys. The code below solved my problem.
        public void XY_AddNewPoint27()
            {
            DateTime timeStamp=DateTime.Now;
            // Add new data point to its series.
            chart2_7.Series["ID01-"].Points.AddXY(timeStamp.ToOADate(),Convert.ToDouble(a_s_Ritsu[cHR,3]));
            chart2_7.Series["ID02"].Points.AddXY(timeStamp.ToOADate(),Convert.ToDouble(a_s_Ritsu[cHR,5]));
            chart2_7.Series["ID03"].Points.AddXY(timeStamp.ToOADate(),Convert.ToDouble(a_s_Ritsu[cHR,7]));

            // remove all points from the source series older than 20 seconds.
            double removeBefore=timeStamp.AddMinutes((double)(10)*(-1)).ToOADate();

            //remove oldest values to maintain a constant number of data points
            while(chart2_7.Series[0].Points[0].XValue<removeBefore)
                {
                chart2_7.Series[0].Points.RemoveAt(0);
                }

            chart2_7.ChartAreas[0].AxisX.Minimum=chart2_7.Series[0].Points[0].XValue;
            chart2_7.ChartAreas[0].AxisX.Maximum=DateTime.FromOADate(chart2_7.Series[0].Points[0].XValue).AddMinutes(10).ToOADate();
            chart2_7.Invalidate();
            }
