Export "Department Expense Comparison" to Excel with Java (Chart & Visualization)
Chart & VisualizationScene 0106
Budget and actual expenses compared per department, computing the variance (Actual - Budget) at each row's end and summarizing in the last row; includes a 3-D bar chart comparing budget vs. actual. Exported as a multi-sheet workbook (Department Expense Comparison / Department Expense Comparison Chart). Implemented declaratively in pure XML — no Java business code required.
About this demo
This demo exports the "Department Expense Comparison" workbook: 1 data sheet(s); MAPPING over 4 columns (部门, 预算, 实际, 差异), 9 formula(s), 1 style rule(s), BAR3D chart on its own sheet. On the Java side it builds 5 data rows and calls exportDepartmentCostCompare() once — everything else is driven by the config.
It belongs to the "Chart & Visualization" group: GRAPH charts — column, line, scatter and radar charts written into a separate sheet, making the workbook multi-sheet.

The core is these four lines: hand the rows to the parser, the parser to the factory, get a typed Service and call it. Copy them straight into your project.
// rows 由业务代码构造（List<JQuickRow>），os 为输出流，见下方完整源码
JQuickParseHandler parser = new JQuickExcelExportXmlParseFactory("sunsetOrange", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);
