JFreeChart is a comprehensive open-source 2D chart library for the Java platform, usable in Swing and JavaFX client applications or on the server side. It supports a wide range of chart types and exports to PNG, JPEG, SVG, PDF, and other formats.
Use cases
- render charts in a Java Swing desktop application
- display charts in a JavaFX application
- generate chart images server-side for web reports
- export charts to SVG or PDF from Java
- plot time series and Sankey charts in Java
When to choose
- you need mature, well-documented charting in a Java application
- you need LGPL licensing that permits use in proprietary software
- you need both client-side rendering and server-side image/vector export
When to avoid
- you need interactive 3D charts (use Orson Charts instead)
- you are not on the Java/JVM platform
- you need JavaScript/browser-native charting
