Waveform chart is not being updated in while loop.

[Randy Zoran]

I have an input to a waveform chart in a while loop and also an event within a case structure in the same loop. It appears that the while loop does not execute until the event becomes true. I don't understand why this happens.

Hello,

I think the problem comes from the fact that you probably need a timeout in your event structure. I would be sure of that if you could send the VI.

Anyway, try to add the "timeout" event in your event structure and wire a number to the hourglass on the top left of the event structure (50 (ms) for example).

Hope this helps !
