HOW-TO Create a grand total (with no groups)
If there is a need for grand totals and no grouping in the project, DynamicJasper provides a way to get that.
Grand totals can be located in the header or the footer of the report
DynamicReportBuilder drb = new DynamicReportBuilder(); //ReportBuilder initialization drb.addGlobalHeaderVariable(columnAmount, ColumnsGroupVariableOperation.SUM); drb.addGlobalFooterVariable(columnAmount, ColumnsGroupVariableOperation.SUM);
Where the parameters passed are:
- The column to use for the calculation
- The operation to apply (SUM, COUNT, etc)
- The style to use for this total (optional)Refer to GroupsReportTest for a working example.
