Made a bit more progress on this project today. I've worked out how to format the plots and how to create a form with tabs. This means I can reduce the footprint of the application and add some other functionality. I've added the ability to change the thresholds on the fly and also a screen showing the raw sensor values being transmitted from the arduino (these are random numbers in my test case in the attached screen shots). I'm still grappling with an error when I try to increase the number of history points that is taking some time to resolve. Any ideas on how to resolve this will be gratefully received!
