JChart2D Library
- License Model: open source (LGPL license)
- Webpage and download: [1]
The library is very easy to use because you don't have to spend a lot of time on making adjustments. You can create for example static line charts and dynamic line charts but you cannot create Pie Charts or Bar Charts.
Code Examples
The follwing code snipped creates a static XY Diagramm
import info.monitorenter.gui.chart.Chart2D;
import info.monitorenter.gui.chart.ITrace2D;
import info.monitorenter.gui.chart.traces.Trace2DSimple;
import javax.swing.JFrame;
public class MinimalStaticChart {
private MinimalStaticChart() {
super();
}
public static void main(String[]args){
// Create a chart:
Chart2D chart = new Chart2D();
// Create an ITrace:
ITrace2D trace = new Trace2DSimple();
// Add the trace to the chart:
chart.addTrace(trace);
// Create the Points and add them to the trace
for(double i=0;i<=10;i+=0.001){
trace.addPoint(Math.cos(3*i),Math.sin(4*i));
}
// Create a frame.
JFrame frame = new JFrame("MinimalStaticChart");
// add the chart to the frame:
frame.getContentPane().add(chart);
// make a few adjustments for the Frame
frame.setSize(400,300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
which looks like this:

The library bla bla bla .....
Code Examples
The follwing code snipped creates a pie chart together with a life update Venn Diagramm

which looks like this:

Other Libraries
The following Java libraries looked promising, but turned out to be not recommendable:
- M$$-Chart commercial license (500 € per license)
- Crash-Chart beta version, still needs a lot of development, crashes frequently
- Bad-Chart bad performance, missing important chart types like xy-Diagrams
