Export "Inventory Level Trend" to Excel with Java (Chart & Visualization)
Chart & VisualizationScene 0107
Registers opening balance / inbound / outbound by month, rolling the closing balance forward (Closing = Opening + Inbound - Outbound) with a summary in the last row; includes a 3-D area chart showing the inventory trend. All statistics and charts are declared in XML. Exported as a multi-sheet workbook (Inventory Level Trend / Inventory Level Trend Chart). Implemented declaratively in pure XML — no Java business code required.
About this demo
This demo exports the "Inventory Level Trend" workbook: 1 data sheet(s); MAPPING over 5 columns (月份, 期初, 入库, 出库, 期末), 9 formula(s), 1 style rule(s), AREA3D chart on its own sheet. On the Java side it builds 5 data rows and calls exportInventoryTrend() 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("forestGreen", 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.
