Hi, I have been trying to create a VI which will allow me to convert a pulsed signal (generated by a tachometer) into a single thickness line, indicating that a revolution has passed. I would like to overlay this line onto the other signals being generated. I am able to detect the falling edge of the signal, but I have not been able to make a suitable line. I have tried creating a new waveform, and fiddling with markers, but neither method has worked for me. Does anyone have any ideas of a good way to do this? My test VI is below.

Make the second plot style vertical lines (plot style: no points, no interpolation, fill to -inf). feed a NaN whener you don't want a line and a "+inf" whenever you want a vertical line. Here's a simple example:

Just part of the learning curve. I'd bet real money (if I had real money) that most people aren't accustomed to discussion forums where there are real answers, rather than just opinions, so they can make mistakes.
