Newbie still has graphing problem.

[Lisa Lord]

I am using a GPIB controller card, which will talk to my HP meter,
and I can get a single reading from the VI, but the loop does not
sample and graph despite the while loop.

I can send anyone willing to help a .jpg or whatever format you like
of a screen print of what I'm looking at. I think that would make
solving this
much easier.

TIA,
A frustrated Lisa.

Lisa,

I have been doing this for almost 5 years now, and I still get confused about graphs and charts. I still go to the helpful LabVIEW example programs and look at the graphing examples to answer questions I have about how to graph a specific application. I guess that comes from my complete lack of understanding of the graph and chart datatypes, but that is easily surmountable with a quick reminder from the examples.

Try that. Look at the examples to see if they can help you solve your question.

Good luck

Guru,
Been there, done that. Thats why I'm here.
As good as the examples are, I'm still missing
a key piece of info.

Sorry, they usually help me.


Did you find out what you needed yet?

Guru,
Yes thank you.
Labiew er found the missing VISA session, that seemed to do the trick!
Thanks all!

Hi,
send a screen capture to labviewer@yahoo.com ... even if a piece of the diagram with the loop will be helpful.

I'd be happy to look at a screen capture or even the vi.

Hi Lisa,
it will be good to have at least
1. an 'error cluster' or 'error dialog' wired to the error output of your hp34..example VI in order to see the description and error code
2. a control to set the input value of your VISA session according with your instrument communication settings.
let me know if still not working

Lab Guy,
Thanks very much for the help. It appears the key was the missing VISA
session.
I'm sure there will be more questions posted, but this was great to see
going!
Thanks again,
-Lisa

Lisa,

I looked at your screen capture and sent an email to your email address, if this didn't work then let me know.
