Do you know whether the graph is supposed to graph real time as the program runs, or at the end when the program is all finished? What I found was that when running the code that you modified for me, the for loop is drastically slowed down I assume because the other VI that it is getting its Queue from takes so much longer to run. As the for loop counts through the graph is not updated. And since it takes so long to get through each for loop cycle, for a very long time the graph just stays empty. So I have a questions for you:
Can the graph update real time so that as the for loop goes so does the graph? How do I make it do that?
