LSUgirl Posted August 6, 2007 Report Share Posted August 6, 2007 Hi, I have a single pie chart my page with some date range text boxes. The user enters a date range and it populates the pie chart. If the user selects another date range, it retrieves the data and creates a chart with 2 pie charts. If the users searches again, I get 3 pie charts. And so on. What is going on? The ldt is always created with one set of 7 rows. It's not a data issue. My code behind: Chart1.Data.Clear(); DataTable ldt = iPDDataAdapterTop5.RetrievePBToDt(0); // if table has label, value, value use thisChart1.DataSourceSettings.Fields.Add(new FieldMap("code_desc", FieldUsage.Label)); Chart1.DataSourceSettings.Fields.Add( new FieldMap("per_stds", FieldUsage.Value));Chart1.DataSourceSettings.Fields.Add(new FieldMap("nbr_stds", FieldUsage.NotUsed)); Chart1.DataSourceSettings.DataSource = ldt.DefaultView; // do this to make mapping workSystem.IO.MemoryStream objStream = new System.IO.MemoryStream(); Chart1.Export(ChartFX.WebForms. FileFormat.Jpeg, objStream);Chart1.DataBind(); Quote Link to comment Share on other sites More sharing options...
