Slow graphical indicator at low sample rates

[andrew_JKTA]

Hi all,

I have the same problem as Will.D from this post:

http://forums.ni.com/ni/board/message?board.id=170&message.id=217090&query.id=224080#M217090

and I followed this article, which I found in the post:

http://digital.ni.com/public.nsf/allkb/5C9D0AEFAE8EA81486256DCF00788B2F

but the problem still cannot be solved.

I have attached a screen shot to show you what I have done. This is all in a while loop wiht a DAQ assistant connected to a waveform graph indicator. Can anyone give me any ideas as to how I can make the waveform graph indicator update faster at low sampling rates?

Thank you very much.

anyone?

Could you show a little bit more code?

The KB article says to configure this before starting the task, but you seem to do it in a loop, if I understand you right. Could you check in what order things happen?

Thanks for the help.

So you mean I should try building what the KB document said before I build the rest of my code?

Thanks again.

The order in which you write the program does not matter, but you should probably make sure that this node executes before the input task executes. THis is done by porpert dataflow. That's how I understand it.

Why don't you show a little bit more of your code so we see the big picture. 🙂
