/**
 * 业务场景 Demo 32：合同签订趋势（企业法务与合同管理）
 *
 * <p>业务场景：企业合同管理系统按月统计签订合同数与平均履约率，柱表示月度签订量、
 * 线表示履约质量，用于法务风险管控与经营例会汇报，主色采用墨绿 #1B5E20。</p>
 * <p>实际图表类型：{@link JChartType#LineBar} 折线柱状混合图（双 Y 轴：左轴合同份数、右轴履约率百分比）。</p>
 *
 * <p>模板：{@code report/biz/32_contract_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\32_contract_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>

Minimal invocation (3 lines)

Skip the full test class — the core is these three lines: bind the chart SVG, execute the template, get the PDF bytes. Copy them straight into your project.

// 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/32_contract_linebar.txt");
