I am in need to change the chart's data title and group title in during for localisation purpose. I am using below code to loop through the reports object and get the chart object
C#
foreach (CrystalDecisions.CrystalReports.Engine.Section section in rpt.ReportDefinition.Sections)
            {
                CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument clientDocument =
               rpt.ReportClientDocument;
                CrystalDecisions.ReportAppServer.ReportDefModel.ReportObjects myCharts;
                myCharts = clientDocument.ReportDefController.ReportObjectController.GetReportObjectsByKind(CrReportObjectKindEnum.crReportObjectKindChart);
                foreach (CrystalDecisions.ReportAppServer.ReportDefModel.ReportObject oldObject in myCharts)
                {
                    if (oldObject.Kind == CrReportObjectKindEnum.crReportObjectKindChart)
                    {
                        CrystalDecisions.ReportAppServer.ReportDefModel.ChartObject oldChart;
                        CrystalDecisions.ReportAppServer.ReportDefModel.ChartObject newChart;
                        oldChart = (CrystalDecisions.ReportAppServer.ReportDefModel.ChartObject)oldObject;
                        newChart = (CrystalDecisions.ReportAppServer.ReportDefModel.ChartObject)oldChart.Clone(true);
                        if (!string.IsNullOrEmpty(oldChart.ChartStyle.TextOptions.DataTitle))
                        {
                            langtran1 = oldChart.ChartStyle.TextOptions.DataTitle.Replace(" ", "");
                            langtran1 = langtran + langtran1;
                            langtran1 = Regex.Replace(langtran1, "[^a-zA-Z0-9_.]+", "", RegexOptions.Compiled);
                            langtran1 = langtran1.Replace(".", "");
                            oldChart.ChartStyle.TextOptions.DataTitle = GetEnumvalues(langtran1);
                            langtran1 = "";
                            clientDocument.ReportDefController.ModifyChartObject(oldChart, oldChart);
                            clientDocument.RefreshReportDocument();
                        }                    
                    }
                }
            }

For the below line
C#
clientDocument.ReportDefController.ModifyChartObject(oldChart, oldChart);
                            clientDocument.RefreshReportDocument();


i am getting exception - The chart data is not valid.

This exception is arising only for the reports having chart type CrystalDecisions.ReportAppServer.ReportDefModel.CrChartTypeEnum.crChartTypeCrossTab

Please help me what i have to do for this to work.

Sivaraman.
