XChart

XChart is a charting Library for Java. While several charting Libraries already exist, most of them require a steep learning curve and the code base is bloated, full of too many "features" and/or very outdated. Inspired by SWTCharts, simplicity is prioritized over everything else so you can quickly make a plot and move on. XCharts can be used in your Swing, Java EE, and Java SE applications. If you're looking for a Java charting Library that is easy to use and does not need every feature under the sun, XChart is for you.
