Ploting graphs

[Oliveira]

I am in trouble while I am trying to plot some data in graphics using labwindows/cvi 8.1.1

I want to plot 2 lines. I don't have any data to plot when the time is 0. I have a device that generates the data that will be plotted, so I want to plot the data continuously.

When I start the data generators I can get the last value of the data and store it in a variable that can be easily accessed by the CVI environment. I receive the data throught a windows component developed by myself.

Can anyone send me an example or help me to solve this problem?

Thank you in advance!

Hi Oliveira,
   Have you used graph or chart display?  I think that if you use Charts, what you want to do comes automatically.  I've found a document explaining this (it is for LabVIEW, but the same applies also to LabWindows).

   I hope this helps... let me know!

It helps me, but, I am a begginer developer in CVI, so I don't know how to do it.

Thank you.

Suggestions and examples are welcome!

Hi Oliveira,
   I'm sorry, but It's been a long time since I don't develop with CVI, now I'm using LabVIEW.  Even if most concepts are portable, of course I can't send you an example about LabVIEW....

    I've searched in the examples provided with CVI, I've found ContAcqSamp-SWTimed , if you want to find it, just go to
  
                help -->  Find Examples...

     hen go to "search" tab and tip "Charts", you'll find some examples about them.  This holds for CVI version 7.1, I actually don't know what is your package and version... (I've Developer Suite 7.1).

   Another example is autostrp , which doesn't need a Daqmx card to work (ContAcqSamp-SWTimed assumes you have an NI DAQ device).

Please, let me know if this helps.... Have a nice day!
