How to Manage property of Chart Expert and Chart Options for ChartObject using .NET RAS SDK.

Hello Friends,

I have created a ChartObject and added it to my sample Crystal Report at runtime using .NET RAS SDK. I have also added table at runtime. Here is the sample code:

           CrystalDecisions.ReportAppServer.ReportDefModel.ChartObject myChartObject;

           CrystalDecisions.ReportAppServer.ReportDefModel.ChartStyle myChartStyle;

           CrystalDecisions.ReportAppServer.ReportDefModel.Section mySection;

           CrystalDecisions.ReportAppServer.DataDefModel.Fields myFields;

           CrystalDecisions.ReportAppServer.DataDefModel.Field myField;

           CrystalDecisions.ReportAppServer.DataDefModel.SummaryField mySummaryField;

            int myFieldIndex;

           CrystalDecisions.CrystalReports.Engine.ReportDocument reportDocument = new CrystalDecisions.CrystalReports.Engine.ReportDocument();

          reportDocument.Load(Server.MapPath("/CrystalReport1.rpt"));

          ISCDReportClientDocument myReportClientDocument = reportDocument.ReportClientDocument;

          System.Data.DataSet ds = generatCR.createDataSet(_); //here I call method to create dataset

          //create xml file for CR

          ds.WriteXml(Server.MapPath("/dataset.xml"), XmlWriteMode.WriteSchema);

          CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo connectionInfo = generatCR.getConnectionInfo(Server.MapPath("/dataset.xml")); //this is the method to get ConnectionInfo

           //creating able for CR - main (columns)

           ISCRTable table1 = DataSetConverter.Convert(ds).Tables[0];

           Table1.ConnectionInfo = connectionInfo;

           myReportClientDocument.DatabaseController.AddTable(table1, null);

           myFields = myReportClientDocument.DatabaseController.Database.Tables[0].DataFields;

           //Create a chart

           myChartObject = new CrystalDecisions.ReportAppServer.ReportDefModel.ChartObject();

           //create a line chart style

           myChartStyle = new CrystalDecisions.ReportAppServer.ReportDefModel.ChartStyle();

           myChartStyle.Type = CrystalDecisions.ReportAppServer.ReportDefModel.CrChartStyleTypeEnum.crChartStyleTypeLine;

           //set the chart style to line chart

           myChartObject.ChartStyle = myChartStyle;

           //set the chart type to advanced chart

           myChartObject.ChartDefinition.ChartType = CrystalDecisions.ReportAppServer.ReportDefModel.CrChartTypeEnum.crChartTypeDetail;

           //set datetime field as condition field

           //get the datetime field

           myFieldIndex = myFields.Find("datetime", CrystalDecisions.ReportAppServer.DataDefModel.CrFieldDisplayNameTypeEnum.crFieldDisplayNameName,

CrystalDecisions.ReportAppServer.DataDefModel.CeLocale.ceLocaleUserDefault);

           myField = (CrystalDecisions.ReportAppServer.DataDefModel.Field)myFields[myFieldIndex];

           myChartObject.ChartDefinition.ConditionFields.Add(myField);

           myField = null;

           //set value as data field

           //get {value field}

           myFieldIndex = myFields.Find("value",

CrystalDecisions.ReportAppServer.DataDefModel.CrFieldDisplayNameTypeEnum.crFieldDisplayNameName,

CrystalDecisions.ReportAppServer.DataDefModel.CeLocale.ceLocaleUserDefault);

           myField = (CrystalDecisions.ReportAppServer.DataDefModel.Field)myFields[myFieldIndex];

           //create a Sum({Customer.Last Year's Sales})

           mySummaryField = new CrystalDecisions.ReportAppServer.DataDefModel.SummaryField();

           mySummaryField.SummarizedField = myField;

           mySummaryField.Operation = CrystalDecisions.ReportAppServer.DataDefModel.CrSummaryOperationEnum.crSummaryOperationSum;

           mySummaryField.Type = myField.Type;

           //add summary field to report client document

           myReportClientDocument.DataDefController.SummaryFieldController.Add(-1, mySummaryField);

           myChartObject.ChartDefinition.DataFields.Add(mySummaryField);

           //set chart coordinates and dimensions

           myChartObject.Left = 0;

           myChartObject.Top = 15 * 15; //1px = 15 twips

           myChartObject.Width = 980 * 15; 

           myChartObject.Height = 500 * 15;

           //get report header section

           mySection = myReportClientDocument.ReportDefinition.ReportHeaderArea.Sections[0];

           //set chart report area to report header

           myChartObject.ChartReportArea = CrystalDecisions.ReportAppServer.ReportDefModel.CrAreaSectionKindEnum.crAreaSectionKindReportHeader;

           //add chart in the report header

           myReportClientDocument.ReportDefController.ReportObjectController.Add(myChartObject, mySection, -1);

           //Set the ReportSource of the viewer to the report in Session

           Session["myReport"] = reportDocument;

           CrystalReportViewer1.ReportSource = Session["myReport"];

           CrystalReportViewer1.DataBind();

Above code is working fine for me and creates a simple line chart.

Now I want to modify chart options, data, text, axis and want to use sub category of Line Chart for e.g. "Line chart with markers data points" using code. I want to know how I can performs modifications in a chart through code which I can do through chart expert and chart options.

Please tell me where I can get more instructions about classes and methods to fulfill my requirements.
