Waveform disappears when zoomed in

[pratheek]

Hi

Everything works as required in my vi, but when zoomed in the waveform plot gets disappeared. Could some one please tell me the reason for this

Thankyou in advance

Best Regards

Hi pratheek,

your VI has quite a lot of problems:

- To your question: the plot vanishes because you use a "default if unwired" tunnel to output the plot data to your graphs.

- Your local variables create race conditions. I'm sure "Restart" local variable will hold the wrong value when you press the button to restart your state…

- Why the hell do you need to set the "Overview Graph" properties as fast as the computer can do? Do you change the X/Y axis properties that fast?

- Why do you need that one-frame sequence structure?

Clean up your VI, remove local variables, don't use "default if unwired" output tunnels!
