Read Serial array then plot it

I appreciate your effort there. My programming is untrained, trial and error, interspersed with flashes of brilliance on rare occasion. The first time I ever sat at a computer was in high school and the computer was a mini computer in a different location. The first task was to login and enter a program using the keyboard and I couldnt understand any of it. I switched to wood shop and whittled a rainbow trout leaping out of the water to snatch a fly.

Years later I had one course in C++ so OOP is not completely foreign. Use it or lose it, so I’m shaking off the rust one line of code at a time. Thanks for your help. I’ll be back with what I do with this.
