Can you create a chart that is "not added at runtime"? No? Better try that first.

C#

DataTable dt = new DataTable();
            dt.Columns.Add("Col", typeof(String));
            dt.Columns.Add("Score", typeof(int));
            DataRow dr = dt.NewRow();
            dr["Col"] = "Col1";
            dr["Score"] = 10;
            dt.Rows.Add(dr);
            dr = dt.NewRow();
            dr["Col"] = "Col2";
            dr["Score"] = 5;
            dt.Rows.Add(dr);

            Chart chrt = new Chart();
            ChartArea chrtArea = new ChartArea("ChartArea1");
            chrtArea.Area3DStyle.Enable3D = true;
            chrtArea.Area3DStyle.WallWidth = 0;
            chrt.ChartAreas.Add(chrtArea);
            Series series = new Series("Series1");
