We are using UltraWebChart to draw pie-chart in our Asp.net application.

It is throwing below error when we try to load specific numbers into the chart.

Exception: System.ArgumentException
Message: Parameter is not valid.

•      We are using Infragistics4.WebUI.UltraWebChart.v11.1 ( Version 11.1.20111.1006)
•      The chart implemented to show three different status. Given below is the test data table and  code snippet for chart binding

DataTable:

Column : LABELX          SERIES1           SORTINDEX

            Pending-11      11                    1

            Active-11        11                    2

            Inactive-83      83                    3

private static void BindDataToChart(UltraChart chart, DataTable dt)

                                {

                                                switch (chart.ChartType)

                                                {

                                                                case ChartType.PieChart3D:

                                                                                chart.DataSource = dt;

                                                                                chart.DataBind();

                                                                                chart.Data.IncludeColumn("SORTIDX", false);

                                                                                break;

                                                                ……

                                                                ……

•  The below table explains a number of scenarios which is causing the error.

•    The system will work fine if any count gets changed or numbers are swapped.   ie  scenario #1 will work fine if  Pending -11, Active -83 , Inactive -11

Any help will be highly appreciated.
