10 Excellent Free Open Source Java Chart Library for Developers

List of Java Charting Libraries

Java offers immense flexibilities in running a number of web applications independent of the running platform and computer architecture. The two and three-dimensional representations through different types of bar graphs provided by Java have enhanced its popularity since its release.

In recent years, Java libraries are being used less for web-based reporting since there are really powerful jQuery and JavaScript charting libraries available for client-side rendering.

However, even now Java software is still run on millions of computers as the Java Charting Library offers varied interesting features to the users and web developers. The users can embed stunning 2D and 3D representations in the web through different types of graphs and charts imported from the Java charting library.

Free Open Source Java Charting Library


This open source Java charting library offers users the maximum alternatives to represent their complex data in a simplified manner. It enables the extensive use of X-Y charts, Pie charts, Bar graphs, Gantt charts, Pareto charts, combination charts, wafer map charts and other special types of charts.

In a nutshell, JFreeChart is a comprehensive charting package providing maximum charting options to the users. Axis, legends, and scales are automatically drawn and, the user can also place various markers on the plotted chart. The charts can be zoomed for a better view and can be regularly updated by the attendants of the Java charting library. The user can download the developer’s guide and follow the applications accordingly.


This is another promising Java Charting library next to the JFree Chart. This charting library occupies very little disk space about less than 100kb and is very useful for designing charts based on scientific data.

The flexibility of JCC Kit enables easy writing of applet programs that presents data on the web page without any prior knowledge of Java programming language. Automatic rescaling, creating legends and up gradation is possible with JCC Kit Charting library.


This Java charting is very useful and simplifies the interface for plotting 2-D charts. Following the basics of JOpenChart library, OpenChart2 offers a variety of charting features including advanced forms of bar graphs, pie charts and scatter plots.


This open-source charting facility is very useful to display different types of charts through JSP’s, Servlet and Swing apps. The developer can download any Servlet container and follow the examples of jCharts.

GRAL Graphing Library

This Java Graphing Library enables high-quality plotting and charting. It can also import data from texts, audios, and videos and the plots can be produced in JPEG, EPS, PDF, PNG and SVG files. Users can also use GRAL for different types of data processing and this library also provides a Java Swing interface.


This lightweight charts and graphs Java API enables to create charts programmatically using Google chart tools. It can be integrated into any web application or Swing, JSP, Servlet or GWT.


This charting library is meant for representing engineering data demanding high precision than colorful presentations. JChart2D, a Java component displays dynamic 2D charts offering automatic labeling scaling.

Users carrying basic knowledge of Java Swing and AWT can use it to the best possible limit. It is preferred over JFreeChart due to its dynamic feature.


This useful open source Java reporting tool helps in delivering rich content on the screen or exporting to HTML, PDF, XML, XLS and CSV files and printer. This 100% Java-based program finds extensive use in various Web and Java applications (JEE) that produce dynamic content. The user can generate reports instantly in the most simplified manner and get them printed.


This is another open source tool meant for generating reports or it can be assigned as Java Report Generator. It provides an on-screen print preview based on data via Java Swing’s Table Model Interface, and reports can either be generated from the printer or can be exported to various formats like PDF, XLS, HTML and many more.


In designing simple three-dimensional charts like bar graphs and scatter plots, Jzy3D graphing library is very handy. This charting library is also useful in creating 2D graphs and plots. There are also provisions to add color maps and different contours beside 3D charts. Jzy3D also enables a wide range of customization through various layout tools.
Different types of projects and jobs need different projections and representations, and Java charting library offers a number of charting tools to represent their data in an understandable manner. All of these charting applications are open source software and can be downloaded for free.

Hope you found this list useful. What java libraries do you use for creating reports and charts?

  1. I feel OpenChart2 to be more useful as it provides a simple interface through which developers can easily create two dimensional charts and plots.

  2. Hi , nice listing of open source library for charts in java.

    java chart demo tutorials on:-


  3. Try out XChart (http://xeiam.com/xchart.jsp) as well. XChart is a light-weight Java library for plotting data that would be a potential alternative to JFreeChart. Its focus is on simplicity and doesn't have every capability that JFreeChart has, but it offers a rich set of charting features including Themes to apply different "skins" to a chart. You can easily create your own Theme by implementing an interface and applying it to a Chart by calling `chart.setTheme(myTheme)`. The jar is only ~86 KB as of the 2.0.0 release, and it has no dependencies. It's licensed under Apache 2.0 and is hosted on Github (https://github.com/timmolter/XChart). Disclaimer: I'm the lead devloper of the project.

    1. Pretty good,but it is pity that haven't had the pie chart :(

  4. Thanks for the comprehensive list. I was going for JFreeChart but now I will give a shot to others as well.

  5. I believe that the post has perfect collection of words and a well research. Its awesome! Thanks for sharing. Waiting for next.

  6. Nice list!" I have to say the JavaFX library from Oracle is pretty good too. I think this should have made the list. Although the graph library itself isn't extensive, it is extendable and applying CSS affords a wealth of possibilities!

  7. Very good list! I think that one more chartinglibrary I found recently and have given it some try is worth mentioning- the ShieldUI Charts. These are free for non commercial usage and have lots of examples and documentation: http://www.shieldui.com/products/chart
    hope you will like it!
