I'm new to labview and I'm having a problem stopping a while loop (running windows XP/2000 with the student edition of labview express 7).I'm doing a data acquisition program where I'm constantly reading in voltage and comparing it to a set point value, when the input voltage goes above the set point, i want the while loop to stop. How do I do this? I already have an LED going on when the criteria is met, but I'm not sure how to actually stop the loop (i.e. change the iteration value from true to false-i guess). If anyone can please assist me with this I would very much appreciate it. I've included my program too.

Thank you altenbach- your example code makes sense and looks cool- I'm opting for the array to indicate the plot colors. You're the best!
