- Fast drawing mode with lower resolution for high performance real-time display - Slow drawing mode for high resolution, high quality printing, image output etc. - Output of charts in EPS,PS, as BufferedImage and (planned) PNG,SVG etc. - Linear, logarithmic and wrapped axes with auto scale. - Scatter plot, Contour plot; (planned) BarPlot, PiePlot... - Plots are fully configurable allowing all advantages of Java2D: Transparency, Scaling, Rotating, Clipping... - Text console allowing full control for keyboard lovers (planned) - Use console or pipe for in-/output (planned)

JChart2D is an minimalistic charting library published under the OSI approved GNU LESSER GENERAL PUBLIC LICENSE. It is designed for displaying multiple traces consisting of tracepoints. JChart2D is centered around a single configureable swing widget: the Chart2D. It is a JComponent one can add to a java swing user interface. Therefore basic knowledge of java awt and swing and the information provided on this site is helpful. If no basic knowledge of swing and awt is given, the example code will give a quick entry as well.

JOpenChart is a free Java Toolkit and library for embedding charts into different kinds of applications, no matter if they are server side, desktop or web applications. Commercial solutions are pretty expensive and at the time I started working on JOpenChart, there was no satisfying open source solution available. Currently, the library provides all the functionality to draw different kinds of charts, like line, bar, pie and plot charts. Additionally, the class structure includes the necessary classes for the encapsulation of sets of data and the classes for all parts of a typical chart, like a coordinate system, coordinate axes, legends, title and chart renderers. I put great effort into a good design, ie understandable, logical class structures, elegant interfaces, use of abstract classes etc. The library is easily extendable to provide your own functionalities. This is best illustrated by noting, that all the Renderer classes, which paint the charts, have about 150 - 200 lines of code. That's pretty easy, isn't it?

Openchart2, based on the original JOpenChart library by Sebastian Müller, provides a simple, yet powerful, interface for Java programmers to create two-dimensional charts and plots. The library features an assortment of graph styles, including advanced scatter plots, bar graphs, and pie charts. New features are added constantly to improve the power of the library. Best of all, Openchart2 is free! The library is licensed under the GNU Lesser GPL, allowing for its inclusion in proprietary software (as long as modifications to the library are released). Furthermore, the developer documentation is available to all.

Charts with Swing This chart implementation provides graphs of one or more functions as Swing components. The design was made to render large amounts of real-time data. Java 5 or newer is required. Please try the Web Start demonstration.

The JCCKit is a small (< 100Kb) library and a very flexible framework for creating scientific charts and plots. JCCKit is written for the JDK™ 1.1.8 platform (except of a Graphics2D renderer). Thus, it is suitable for scientific Applets and for PDA's running a PersonalJava™ implementation. JCCKit is an offspring of my lecture The Art of Developing Scientific Java Applets held at the University of Basel, Switzerland, in the winter semester 2002/03. See lecture 12 and 13 which explains the basic architecture of JCCKit. Purpose and Features The main purpose is to provide a flexible kit for writing applets and application with the need for visualizing scientific data. If you are looking for a lean scientific chart and plot library without all the unwanted bells and whistles of the heavy competitors try JCCKit. The key features of JCCKit are: * small (< 100Kb jar file) * highly configurable due to a sophisticated configuration concept * extensible (1/3 of all classes are interfaces or abstract classes.) * automatic updating if data changes * easy programming of dynamic charts and plots * automatic rescaling if canvas size changes * out-of-the-box applet for presenting static data on a web page without needing knowledge of the Java™ programming language. * automatically generates a legend * supports o logarithmic axes o non-numerical tic labels o different line styles, colors, and thicknesses o different symbols o different fonts, font styles, colors, and text orientations o vertical and horizontal error bars o vertical, horizontal, and stacked bar charts * supported devices o AWT Graphics context o AWT Graphics2D context (needs Java™ 2 platform) o Off-Screen image creation (need J2SE 1.4 or higher) (see section 2.5 of the User Guide) o SVG (Scalable Vector Graphics)

jCharts is a 100% Java based charting utility that outputs a variety of charts. This package has been designed from the ground up by volunteers for displaying charts via Servlets, JSP's, and Swing apps. First release was in December 2000.

E-Gantt Library E-Gantt is a Gantt Chart library for Java Swing / Scheduling Visualization tool. The library is typically used for editing and visualizing complicated work schedules. The library E-Gantt has been succesfully integrated in many open source projects and large commercial projects with-in the following industries: * Scheduling Research * Medical Research * US Military Defense Projects * Network Administration tools The library is developed as a pure java component which integrates well with the components with-in swing, the component itself is mostly used with-in a JTable with the various flavours possible.

The Google Chart API lets you dynamically generate charts. To see the Chart API in action, open up a browser window and copy the following URL into it: http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World Press the Enter or Return key and - presto! - you should see the following image:

Welcome To JFreeChart! JFreeChart is a free 100% Java chart library that makes it easy for developers to display professional quality charts in their applications. JFreeChart's extensive feature set includes: * a consistent and well-documented API, supporting a wide range of chart types; * a flexible design that is easy to extend, and targets both server-side and client-side applications; * support for many output types, including Swing components, image files (including PNG and JPEG), and vector graphics file formats (including PDF, EPS and SVG); * JFreeChart is "open source" or, more specifically, free software. It is distributed under the terms of the GNU Lesser General Public Licence (LGPL), which permits use in proprietary applications.

Prefuse is a set of software tools for creating rich interactive data visualizations. The original prefuse toolkit provides a visualization framework for the Java programming language. The prefuse flare toolkit provides visualization and animation tools for ActionScript and the Adobe Flash Player.
