Why panel2 didnt remove the chartpanel?

Question

In my Java application, I just use two different panels named as Panel1, Panel2. Both panels have their own ChartPanel from JFreeChart to generate dynamic chart. If I want to clear this by using,

    if(Panel1.getComponentCount() != 0) Panel1.remove(Graph.CPanel);
    if(Panel2.getComponentCount() != 0) Panel2.remove(Graph1.CPanel1);
    Panel1.repaint();
    Panel2.repaint();

the above code mean, it just remove panel one content. Panel two still show the chart panel, but that's not running. Why panel two didn't remove its content?

Please learn common [Java naming conventions](http://java.sun.com/docs/books/jls/second_edition/html/names.doc.html#73307) (specifically the case used for the names) for class, method & attribute names & use them consistently. — Andrew Thompson, Jan 24 '14 at 11:20
For better help sooner, post an [MCVE](http://stackoverflow.com/help/mcve). But do the MCVE using simple colored (JSE) panels first. — Andrew Thompson, Jan 24 '14 at 11:21
@Rahul Generally best to point the OP to the MCVE/MCTR document at times like this, otherwise we tend to get bits and pieces of uncompilable code snippets. — Andrew Thompson, Jan 24 '14 at 11:23
@Rahul, then can you give sample code to remocve chartpanel from the jpanel? — A.Mohamed Bilal, Jan 24 '14 at 11:44

While you can chose to remove the view component, which requires revalidate(), a better choice is to update the model and let the view respond. Some related examples are cited here.

      Panel1.removeAll();
      Panel2.removeAll();

The above statements remove all components in those panels successfully.
