Not sure if this works, but I think it should:
Create a timer
public static final int INTERVAL = somevalue;
timer = new Timer(INTERVAL, new ActionListener() {
               public void actionPerformed(ActionEvent evt) {
if (done) {
timer.stop();
model.setDataVector(....,....);
suppose the method you are running is call theMethod(), then:
     class ActualTask {
          ActualTask() {
     theMethod();
done = true;
     public void go() {    //download the swingworker class from http://java.sun.com/docs/books/tutorial/uiswing/misc/threads.html
          final SwingWorker worker = new SwingWorker() {
               public Object construct() {
                    done = false;
timer.start();
                    return new ActualTask();
          worker.start();     
So, this is running the timer on a thread. You can do other stuff at the same time.
