To build an area chart for credit coverage trends, start by creating a PDF file named 03_area.pdf. You will need a template file, report/credit_report_03_area.txt, containing a bound placeholder and various sections for displaying credit information. This template uses the JPdfX language, a jquick-pdf HTML-like template language, which can be edited separately from the code.
To render the area chart, you will also need one Java class, JQuickCreditReport03AreaTest, responsible for binding the data and rendering the PDF file. This class relies on the jquick-pdf library, which is built on Apache PDFBox and requires Java 8 or higher. The only dependency needed is io.github.paohaijiao:jquick-pdfx:4.2.0.
Once you have the template file and Java class set up, you can proceed to fill in the placeholder with the necessary credit information, such as the enterprise credit assessment report number, evaluation date, enterprise information, financial data for the last four years, and other relevant details. By following these steps, you will successfully create an area chart for credit coverage trends.
