			}
		});

		// pack and display frame
		JFrame f = new JFrame();
		f.getContentPane().add(plot);
		f.pack();
		f.setLocationRelativeTo(null);
		f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		f.setVisible(true);

	}

}

Its work with ein little Patch for JavaPlot.jar
But the Mouse postition ist on start on MouesOver not correct.
