There is a lot of code. I wasn't the initial designer of it either. I came into a pre-made VI. We're talking to multiple devices, and doing a lot of analysis inside the VI. Our front panel is loaded with stuff. More than a page to display it all. It's what the boss wants though so I'm not going to complain. It's actually not that messy, there's just so much there. I also realized that I had to change the .png I posted. My subtraction needed to happen outside the loop. Everything works perfectly now. It may not be the best possible way to code it, but it works how it's supposed to so for now that's all that matters 🙂
