    how it's possible create a chart with multiple line series?

    for example in my db I have:

    Datetime                     Value
    06/10/2011 06:00              8
    06/10/2011 06:10             12
    06/10/2011  06:15            9
    06/10/2011  06:18            6
    06/10/2011   06:21          9

    I want create multiple line series for selected datetime Range where the x-axis is DateTime and the y-axis Value.

    I have tried like this but its not plotting its showing only empty series..
                    series = new ChartSeries();
                        series.Type = ChartSeriesType.Line;
                        series.Name = "RTD"; series.Clear();
                             ChartSeriesItem item = new ChartSeriesItem();

                     item.YValue = Convert.ToDouble(Sqlds.Tables[0].Rows[i][0]);
                    chart1.PlotArea.XAxis[index].TextBlock.Text = DateTime;
                chart1.PlotArea.YAxis.AxisLabel.TextBlock.Text = "DateTime";

                chart1.PlotArea.XAxis.AutoScale = false;
                chart1.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.LongDate;
                chart1.PlotArea.XAxis.Appearance.CustomFormat = "mm/dd/yyyy hh:mm:ss";
                chart1.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 90;
                //Axis Y
                chart1.PlotArea.YAxis.AxisLabel.TextBlock.Text = "Value";

    Hello Prasoon,

    I prepared a sample page where I use RadChart with two Line series and populate them with some random items.

    If you wan tto know how you can create a chart with more than one series (in general), you can use a "for" loop and create a single series on each iteration and then add it to the chart's Series collection. On the other hand, if you have problems implementing a specific scenario, with multiple Line series, could you explain it to me in short, so I can give you some suggestions? You can also modify my page to show me your case and send it back to me.
