Changing swing components

Hi, I have a swing gui that contains graphs, which are just modified
JPanels. I want to switch one of the graphs while the program is
running. I have tried to just switch the reference of the old graph to
the one, but this has no effect.

I have also tried removing the old graph and then adding the new one to
the container. This works a slightly better: the old graph disappears,
but the new one won't appear until the window is resized.
I'm not very familiar with swing, so any help would be great. Thanks!!!

After switching the panels you'll have to make sure the container is
revalidated.
Invalidate the parent container and then call validate on it. Or if you
want to make sure the layout is updated immediately, call doLayout() on
the parent container.

Since this is a JComponent, you can just call revalidate().
