{
CrystalDecisions.ReportAppServer.Controllers.ReportObjectController boReportObjectController = boReportClientDocument.ReportDefController.ReportObjectController;
CrystalDecisions.ReportAppServer.ReportDefModel.ChartObject boChartNew = (CrystalDecisions.ReportAppServer.ReportDefModel.ChartObject)boChartObject.Clone(true);

CrystalDecisions.ReportAppServer.ReportDefModel.ChartStyle boChartStyle = boChartNew.ChartStyle;
boChartStyle.TextOptions.Title = newChartTitle;  // Set the new chart title here
