Overview

Orson Charts is a 3D chart library for the Java™ platform that can generate a wide variety of 3D charts for use in client-side applications (JavaFX and Swing) and server-side applications (with export to PDF, SVG, PNG and JPEG).

Key features include:

• multiple chart types: pie charts, bar charts (regular and stacked), line charts, area charts, scatter charts and surface plots;
• mouse-enabled chart viewers in JavaFX and Swing provide 360 degree rotation and zooming for precise end-user view control;
• configurable tool tip support;
• interactive charts (mouse event support on all chart elements);
• flexible data sources;
• JSON format data import and export;
• regular and logarithmic axis scales;
• auto-adaptive axis labeling;
• value and range marker annotations
• support for PDF, SVG, PNG and JPG export of charts for reporting;
• a clean and well-documented API with a high degree of chart configurability.

Orson Charts is very easy to use, and includes comprehensive Javadocs. It is licensed under the terms of the GNU General Public License version 3 or later. Orson Charts requires JDK/JRE 11 or later. To use Orson Charts with JavaFX requires the Orson Charts FX extension project.
