Zeroing a Waveform Plot with a Front Panel Control

[Tebefia]

I am reading an Analog Input waveform, and have a Front Panel control button that I want to use to zero the signal plot whenever I click on the button.  I know am supposed to use invoke method or property method, but have no ideal on how to go about it.  Does anyone know what exactly am supposed to do to achieve this?

I would appreciate any help in this regard.

If you are having difficulties with basic problems like this, I would suggest you work through at least the first LabVIEW tutorial series that I've got in my sig. This will save you a lot of time now and in the  future.

Camerond, if it is that basic enough to you, then you would have be more humble and kind to answer my question, rather refer me to read tutorials. If you care to know, I have gone through Labview Core 1 & 2.

Hi Tebefia,

as Cameron suggested you should go through Basics courses offered for LabVIEW.

Then you would know where to find exampleVIs for LabVIEW. And you would be able to search in those huge collection of VIs for a suitable example. And then you would find that example that explains how to use charts and graphs (including clearing them)!

Btw. you should also note what kind of indicator you use, as charts and graphs behave different! (Well, you surely know about that, as you already have gone through those mentioned basics courses...)

Edited:

You should also define the word "zeroing"! Do you intend to clear a plot on a graph or do you need to subtract an offset or to multiply by zero?

The better the question the better the answer...

Good! LabVIEW Core 2, Lesson 5, pp. 5-2 to 5-4.

Oh, and graphs and charts are covered in Core 1, Lesson 4H.

It's got nothing to do with humility. guess I've always believed in the "Give a man a fish" proverb:

Give a man a fish and he eats for a day. Teach a man to fish and you've fed him for a lifetime (unless, of course, he doesn't like sushi -- then you also need to teach him how to cook. ).
