Projects / GRAL


GRAL is a library for creating high quality plots and charts in Java. Many plot types are available like scatter plot, bubble plots, line plots, area plots, pie charts, and bar charts. Additionally, GRAL can exchange and process data (smoothing), and various plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.

    Release Notes: This release brings many important API changes and changes to the version control and build system: the API changed because plot settings were replaced by regular Java properties. Be aware that this will break legacy code. The version control system was migrated from ?Subversion to ?git, and the old repository will be faded out. ?Gradle replaces Maven as the build system. However, Maven projects can still get all versions of GRAL from the Maven repository.
