You probably missed the setVisible method

JPanel mainpanel=new JPanel();
	final JPanel main = new JPanel(new BorderLayout());
        final JPanel optionsPanel = new JPanel();
 	cirarc12 c2=new cirarc12();
	c2.setPreferredSize(new java.awt.Dimension(100,100));
	optionsPanel.add(c2,BorderLayout.CENTER);
	main.add(chartPanel, BorderLayout.NORTH);
        //main.add(c2,BorderLayout.CENTER);
     	mainpanel.add(main,BorderLayout.CENTER);
	mainpanel.add(optionsPanel,BorderLayout.CENTER);
	myframe.add(mainpanel);
	myframe.pack();
        //following line missing in your code
        myframe.setVisible(true);
