Export "Monthly Sales Matrix" to Excel with Java (Chart & Visualization)
Chart & VisualizationScene 0110
A sales matrix for three products across January-March, summarizing by month in the last row; includes a surface chart showing the two-dimensional (Product × Month) distribution. Exported as a multi-sheet workbook (Monthly Sales Matrix / Monthly Sales Surface Chart). Implemented declaratively in pure XML — no Java business code required.
About this demo
This demo exports the "Monthly Sales Matrix" workbook: 1 data sheet(s); MAPPING over 4 columns (产品, 1月, 2月, 3月), 6 formula(s), 1 style rule(s), SURFACE chart on its own sheet. On the Java side it builds 4 data rows and calls exportMonthlyProductMatrix() 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.

}Minimal invocation (4 lines)
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("turquoise", rows, os);
JQuickFactory factory = new JQuickXmlFactory(parser, XML);

Formats (FORMAT), formulas (FORMULAS) and styles (STYLE) are all declared in this XML, fully decoupled from the Java code. The full config is below — copy it as-is.
