JFreeChart

JFreeChart is a simple and practical chart library specially designed for Java platforms that allows the creation of a wide variety of both interactive and non-interactive charts.

The application also provides you with various chart examples that can be easily exported to PDF, Canvas or SVG format with minimum effort.

Because of its intuitive and simple interface, JFreeChart supports pie charts (2D and 3D), bar and line charts, scatter plots, Gantt charts, combined plots, statistical and financial charts, etc.

The main window of the application is quite simple and provides you with well-organized menus and settings. On the left side of the window, you are able to access all the charts you are interested in, then navigate to the Memory Usage tab.

A graph model is displayed in the main screen of the application with a personalized description shown to the bottom of the window. Because all the charts are organized in specific categories, you can easily search the graphs you are interested in.

Although JFreeChart can be used in various applications, servlets and JSP servers, the utility is worth having when you need to create graphs and charts so you can emphasize the price evolution for a determined period of time or simply compare two different elements. What's quite interesting is that you can easily place various markers and annotations on the selected graph plot.

The previously mentioned application comes with support for many output types, including Swing components, image files such as PNG and JPEG and vector graphics file formats like PDF, EPS and SVG.

All things considered, JFreeChart is a simple, reliable and effective utility that provides you with well-organized charts and enables you to quickly create interactive graphs, then export them to PDF or SVG format.
