use chart as Graph

[SamirG]

I am capturing 16 channel using DAQ - 6368 card. All channels are are measuring voltage or current signals. I am capturing approx 10 second of data.  I like to use chart as a graph to use cursor to analyse after capturing data. I could also use sweep chart which has a cursor like feature that I am not sure how to control it. Thank you very much in advance.

Samir,

If you right-click on a chart and select Visible Items>Graph Palette you should have cursors available to analyze your signals. Have you tried that?

Eric,

Thank you very much for responding. I tried Visible Items>Graph Palette but I did not see cursor. I was able to use zoom in/ Zoom out and payne window.

Oops! You can't do that with charts. See the link below.

Hello Eric,

It seems like a great solution but hard to follow logic flow. Please see attached my VI. It will be great if you calrify.

 Thanks,

Just to clarify- I am having trouble converting chart to Graph. I could work with Graph property node for cursor

Well, for one thing your graph terminal is outside the loop, so nothing will be shown until the loop ends. For another thing, you're not actually appending your new data to your old data. You should be appending your data to the previous set of data (which comes from the shift register) and pass that into the next loop. Do you know how to use shift registers? Have you taken a look at the LabVIEW Help on shift registers and the shipping examples?
