Trouble with real time chart

[VI_Joe]

I want the x-axis of my chart to display total elapsed time.  Why do the seconds and minutes flicker when the delay is set at a small number?  I started with the example Real-Time Chart.vi and made modifications.

Any ideas on how to get rid of the flicker?  My VI is attached.  The chart will have to be cleared manually - didn't take the time to do it pragmatically.

Thanks in advance.

hi

i can t look at your code right now but I guess that flickering occurs because you have large update rate for the graph... you can decrease that (decimate some points if you acquire too many or put some delay, etc)

I changed chart history length to 1000 and I still get flicker.

The flicker goes away if I wire the delay into the property node like in the example Real-Time Chart.vi; but that doesn't simulate my application.

Any other ideas?

I solved the flicker problem by updating the property node with elapsed time/loop count.

See the attached.
