store and plot

[Mathias_P]

Greetings LabVIEW experts,

I am very new to LV and I have a question that might seem trivial to you. I have looked around in the forum, but havent found quite what I am looking for.

I am running a while loop and on every run I generate a current and a voltage value. I would like to store them in a text file after the loop is done (or during, but it seems like after is faster) and I want to plot the data while I run it. right now I plot the data with a waveform chart, but it does not start over on every run and they are both plotted as a function of time rather then I(V).

Does anyone have a good suggestion on how to do these things?

Attached is what I have so far

Hi Mathias,

to plot I=f(V) you should use an XY-graph. Wire the voltage data as X and I as Y and you're (nearly) done...

Please look here for differences of charts and graphs:

Thanks Gerd. I can now plot data in a scope and a chart. I still dont quite get the clearing of the scope, but I have an example so I will sort it out.
