Intensity Chart Display refresh Bug?

[X.]

No CAR, no joy. I wouldn't hold my breath.

Hi,

Thank you for the question. Our R&D team is aware of the issue. Currently the best next step is to use the workaround or use a property node set to visible to make the chart invisible when it's tab is not shown and visible when the tab is shown.

I hope this helps.

The workaround is not working properly for my use case. I need to put the waveform chart over the intensity chart. Please find attached VI to see buggy behaviour.

Could you please provide me some workaround to fix this?

@Marek_Santavy: this looks to me like an entirely different bug to me, although the underlying cause might be similar. As a far I can see, in my case, trying out your VI, I do not need to Tab to actually see some horrible glitches that make this combo totally useless IMO.

Thank you for the update. It appears that there is definitely still a glitch. What is the desired effect you are looking for and what are you attempting to implement? I think that knowing a bit more about your application may help us to figure out the best way to go about displaying the data.

Please see the forum below which discusses overlapping front panel objects and using tab control

Lastly, I would recommend creating a new forum post for your particular problem, as this one was created over two years ago and may not be getting as much traffic.

Thanks!

@DollarBrill: is there a CAR for the original report? If yes, what is it?

I did get one from Josh_B1 who said that R&D is "aware of the issue".

Thanks.

PS: I don't see how the thread you are linking to is at all relevant. Have you actually checked it out?

Please find attached screenshot which represents my goal to achieve stacked the intensity chart under the waveform chart.

@Marek_Santavy: this is not an easy workaround, but you might want to give it a try if you are desperate... The Intensity Graph (not the Chart) has a property called "PlotImages.Front" which you  can pass a Picture to. So if you can manage displaying your chart into a graph (with a rolling buffer of your own), and build your graph into a picture (with the usual Picture tools), then you might be able to achieve your goals. The advantage is that by definition, the graph will be aligned with the Intensity Plot.

My 2 cts.

@X.: thank you for your hint. The thing is that I want to update the intensity graph/chart as soon as possible (25+ fps) to achieve great user experience with smoothness of updates. Intensity graph/chart's strip charting is not smooth enough and suffers from irregular speed of updates. It is not that bad, but it hurts your eyes when it happens. That is why I want to use sweep charting, which seems to be smooth enough for my purpose.
