LiveGraph is a framework for real-time data visualisation, analysis and logging. It has a real time plotter that can automatically update graphs of your data while it is still being computed by your application. LiveGraph reads files in a simple CSV-style format. For applications developed in Java, LiveGraph additionally provides an API that handles all data logging and persistency issues. LiveGraph uses only very few computational resources for the updates as it is has specialised caching techniques. Transformation of data series between Linear, logarithm, unit interval, and time-plot transformations are supported.

jFreeChart is a widely used open source charting library. Its flexible design is easy to extend and targets both server-side and client-side applications. It supports many output types, including Swing components, image files (PNG and JPEG) and vector graphics file formats (including PDF, EPS and SVG). It may not provide real time charts, updating the dataset once per second is fine. Refreshing the chart less than a second will result in high cpu load. <A HREF="http://www.ujihara.jp/jbyjsharp/jfreechart/" target="_blank">jFreeChart.NET</A> - JFreeChart ported on .NET.
