/**
* 业务场景 Demo 41:多指标复合折线柱状混合图(工业经济运行监测)
*
* <p>业务场景:工业经济运行监测平台按月复合展示工业产值与单位产值综合能耗,柱表示月度产值、
* 线表示能耗强度,用于研判「增产」与「降耗」是否脱钩,主色采用深紫 #6A1B9A。</p>
* <p>实际图表类型:{@link JChartType#LineBar} 折线柱状混合图(双 Y 轴:左轴产值亿元、右轴能耗强度)。</p>
*
* <p>模板:{@code report/biz/41_composite_linebar.txt};图表以 SVG 文本形式绑定到模板的
* {@code ${svg}} 占位符,输出到 {@code D:\test\biz\41_composite_linebar.pdf}。</p>
*
* <p>图表尺寸说明:图表按 700pt × 380pt(宽 × 高)的横版比例设计;模板中 {@code <svg>}
* 只声明宽度、不声明高度,因此宽度被页面自动收窄时高度会按原比例同步缩放,不会纵向拉伸变形。</p>

不想读完整测试类?核心就是这三行:绑定图表 SVG,执行模板,拿到 PDF 字节流。可直接复制到你的项目里。
// config 可省略;svg 来自 JChartRendererFactory.renderChart(...),见下方完整源码
factory.bind("svg", svg);
byte[] pdf = new JQuickPdfFactory(config).executeResource("report/biz/41_composite_linebar.txt");模板文件 · 41_composite_linebar.txt
类 HTML + 内联 CSS 的模板语法,绑定数据后渲染为 PDF。下方为完整模板,可直接复制,也可下载原始文件。
