Data points insertion error. Only 1 Y values can be set for this data series

Hi,

I am creating the spider chart using following data

SourceData:
Subject 	Marks
S1	70
S2	50
S3	66
S4	87
S5	70
S6	87
S7	77

Chart1.DataSource = SourceData;
for (int a = 1; a < SourceData.Columns.Count; a++)
                {
                    String strProdName = SourceData.Columns[a].ColumnName;&#9;
                    Chart1.Series.Add (strProdName);  //Name of the series  
                    Chart1.Series[strProdName].YValueMembers = strProdName;  
                    Chart1.Series[strProdName].XValueMember = SourceData.Columns[0].ColumnName;  
                    Chart1.Series[strProdName].ChartType = SeriesChartType.Radar;

                     
                    Chart1.Series[strProdName].BorderWidth = 3;
                    Chart1.Series[strProdName].Enabled = true;
                    Chart1.Series[strProdName].BorderColor = Color.FromArgb(randonGen.Next(255), randonGen.Next(255), randonGen.Next(255));
                    Chart1.Series[strProdName]["RadarDrawingStyle"] = "Line";
                }

                Chart1.ChartAreas[0].AxisX.MajorGrid.Enabled = false;              
                Chart1.ChartAreas[0].AxisY.LineWidth = 1;

                 //Bind the datasource
                Chart1.DataBind();


While binding the data to chart control I am getting the following error
System.ArgumentOutOfRangeException: Data points insertion error. Only 1 Y values can be set for this data series.
Parameter name: dataSource


Any ideas?

I understand but what I'm trying to say is that your posted code is not the problem per se. How is SourceData actually filled in your code?

Could it be a problem in your SourceData? I tried with this and it works!
DataTable SourceData = new DataTable();
SourceData.Columns.AddRange(new DataColumn[]{new DataColumn("Subject", typeof (string)), new DataColumn("Marks", typeof (int))});
SourceData.Rows.Add(new object[]{"S1",70});
SourceData.Rows.Add(new object[]{"S2",50});
SourceData.Rows.Add(new object[]{"S3",66});
SourceData.Rows.Add(new object[]{"S4",87});
SourceData.Rows.Add(new object[]{"S5",70});
SourceData.Rows.Add(new object[]{"S6",87});
SourceData.Rows.Add(new object[]{"S7",77});
