I am having trouble getting the graph to be live (I want it to update automatically every second). Below is the code I am using to create the graph how can I make this a live graph?

Thank you for the link but as I am new to java I am having trouble understanding what changes I need to make from looking at your link. is there anything specific I could add to to get the graph to refresh or update itself constantly.
