Monthly Revenue and Net Profit: A Dual-Line Chart PDF

jquick-pdf by example — demo #16 of 184. Every article in this series ships one complete, runnable demo: a template file and a Java class. No snippets, no omissions.

The classic monthly operating review page — twelve months, two series, one shared axis.

This document belongs to the Business chart series set.

What you'll build

  • A PDF written to D:/test/biz/16_monthly_revenue.pdf
  • A template file (report/biz/16_monthly_revenue.txt) with 1 bound placeholder
  • A detail grid of 6 rows × 4 columns, laid out with width:100% so it fills the text area
  • One self-contained Java class (JQuickBiz16MonthlyRevenueTest) that binds the data and renders the file

Prerequisites

Java 8+ and one dependency — jquick-pdf is built on Apache PDFBox, not iText:

<dependency> <groupId>io.github.paohaijiao</groupId> <artifactId>jquick-pdfx</artifactId> <version>4.2.0</version> </dependency>

Coordinates: io.github.paohaijiao:jquick-pdfx:4.2.0.

Step 1 — the template file

JPdfX is jquick-pdf's HTML-like template language. It lives in its own file (src/test/resources/report/biz/16_monthly_revenue.txt) instead of a Java string, so designers can edit it without touching code.

<pdf> <body> <div style="background:#2F5597; padding:14px; borderRadius:4px; marginBottom:10px; keepTogether:true"> <div style="display:flex; justifyContent:space-between"> <div style="width:300px"> <h1 style="color:white;

Step 2 — the Java class

Step 3 — run it

The class is a JUnit test, so run it with Maven:

mvn -pl jquick-pdfx test -Dtest=JQuickBiz16MonthlyRevenueTest

…or call the test method from a main wrapper if you want a plain entry point:

public static void main(String[] args) throws Exception { new JQuickBiz16MonthlyRevenueTest().biz16MonthlyRevenue(); }

Output: D:/test/biz/16_monthly_revenue.pdf

How it works

Binding a chart SVG into the template

The chart is not a bitmap — JChartRendererFactory.renderChart(...) returns an SVG string, and the template embeds it with a single <svg> element bound to ${svg}. That means the chart stays vector-sharp at any zoom level, and it participates in normal flow layout instead of being stamped on top of the page.

  • Declare only the width on <svg>; the height is derived from the chart's aspect ratio, so the chart never stretches vertically.
  • Open config.getLayoutConfig().setFlexLayout(true) if the template centers the chart with display:flex.
  • Bind the SVG string with factory.bind("svg", svg) — bind() is pure data injection and never re-parses markup. 
String svg = JChartRendererFactory.renderChart(JChartType.LINE, option); JQuickPdfFactory factory = new JQuickPdfFactory(config); factory.bind("svg", svg); byte[] bytes = factory.executeResource(TEMPLATE);

Making the table fill the text area

Tables default to content width, which leaves a ragged right margin on a formal document. Setting width:100% on the <table> makes it span the full text area; percentage widths on the first row's cells then distribute the remaining space across columns.

  • Set width:100% on <table> and give explicit widths only to the leading columns.
  • Label columns need around 100px so labels like Taxpayer ID do not wrap.
  • Leave the last column without a width so it absorbs rounding remainder. 
<table style="width:100%; fontSize:9pt"> <tr> <td style="width:100px; padding:5px">'Taxpayer ID'</td> <td style="padding:5px">${taxNo}</td> </tr> </table>

Template syntax cheat sheet

Syntax Meaning
<list style="listStyleType:decimal"><li> Ordered or unordered list items.
<td style="padding:4px; border:1px solid #C3CDD8"> Cell styling. A <td> holds text only — no nested blocks.
factory.bind("k", v) Injects plain text into the context; markup inside a value is dropped.
'literal text' A single-quoted string is a literal — whatever is inside is printed verbatim.
${var} An expression. It must sit outside the quotes: 'No: '${docNo}.

Gotchas worth remembering

  • The footer format accepts exactly one %d.
  • Keep <!-- ... --> comments short — long ones can silently blank the render.
  • Use the full-width ￥, not ¥, or the character may render as ?.
  • Compute money with BigDecimal, round once, and derive 大写 from the rounded value.

Output

Wrap up

You now have a template file, a Java class and a PDF — all three reproducible from a clean clone. Swap the placeholder blocks for real data (or for real seal images) and the layout does not move.
