Refresh problem

[ncr7]

I am trying to get this GUI to work to where after you choose a file it shows the graph automatically after the txt file is choose. I have it showing up but it only shows up after I resize it. I'm thinking I have a .setVisible in the wrong spot or I am missing something in the code.

// AvsI.java
//Creates GUI to eventually show Semimajor axis vs Inclination graph.

figured it out, should have a Panel.setVisible(true); inside the actionlistener.
