新手请教Jpanel中添加统计图

Sale1 s1 = new Sale1();
Sale2 s2 = new Sale2();
Sale3 s3 = new Sale3();

panel_1.add("s1",s1);
panel_1.add("s2",s2);
panel_1.add("s3",s3);

}

@Override
public void mouseClicked(MouseEvent e) {
if(e.getSource()==label1){
p1.show(panel_1, "s1");

}else if(e.getSource()==label2){
p1.show(panel_1, "s2");

}else if(e.getSource()==label3){
p1.show(panel_1, "s3");
}
label1.setForeground(Color.BLACK);
label2.setForeground(Color.BLACK);
label3.setForeground(Color.BLACK);
JLabel label = (JLabel) e.getSource();
label.setForeground(Color.WHITE);

}
卡片布局已经做好 想在Sale2中添加条形统计图

就是这种效果
