How to bind array values to make 2 lineseries line chart please ?

[Pierre]

I want to bind on one array to draw a 2 lines chart like

            decimal[] pumpA_array = { 18.6m, 26.5m, 25.8m, 24.3m, 24.9m, 23.2m, 22.0m, 22.4m, 22.9m, 21.7m, 21.2m, 20.2m };
            decimal[] pumpB_array = { 5m, 10m, 15m, 20m, 25m, 30m, 35m, 30m, 25m, 24m, 22m, 20m };

 

 

How must i bind to my array's to get 2 lines like Attached image file please ?

In the telerik example datasource get only one array OR it is declaratively...

 

THANKS for your help

Hello Pierre,

You can only data bind a Chart instance with a single data source. In your cease you need to transform your two arrays in a single IEnumerable data source or DataSet (review the following example http://demos.telerik.com/aspnet-ajax/htmlchart/examples/databinding/bindtodataset/defaultcs.aspx) then data bind the chart with it.

Hello Stanimir,

As you say, it's OK !

 

Great THANKS

 

PS: My working example:

            DataSet ds = new DataSet("PumpPressure");
            DataTable dt = new DataTable("PumpA");
            dt.Columns.Add("ID", Type.GetType("System.Int32"));
            dt.Columns.Add("ValuePumpA", Type.GetType("System.Decimal"));
            dt.Columns.Add("ValuePumpB", Type.GetType("System.Decimal"));
            dt.Columns.Add("ValuePumpC", Type.GetType("System.Decimal"));
            dt.Columns.Add("ValuePumpD", Type.GetType("System.Decimal"));
            for (int i = 0; i < 12; i++)
            {
                dt.Rows.Add(i,i*1.5m,i*2m,Math.Sin(i)*2,Math.Cos(i)*3);
            }

            ds.Tables.Add(dt);

            RadHtmlChart1.DataSource = GetData();
            RadHtmlChart1.DataBind();
