QN Plot - Swing charts for Java

QN Plot provides high performance graph implementation as swing components. It is intended to render large amounts of real time data as graphs.

QN Plot requires Java 5 or higher. All QN Plot classes are thread safe and supports high precision plotting by using BigDecimal data.

Following shows how to create a sample graph using 5 random co-ordinates.

Graph graph = new InteractiveGraph(); swingComponent.add(graph); Function f = new Function("sample"); graph.addFunction(f); int j = 5; while (--j >= 0) {     BigDecimal x = new BigDecimal(Math.random());     BigDecimal y = x+3;     f.addPoint(x, y); } graph.render(); graph.repaint();

The only problem is that the developer guide for JFreeChart is not free! Currently it costs $48.75 per developer for the developer guide (I wonder how that is enforced).  There is also a single site license worth $487.50.
