Plotting vakues in realtime

[Pahee]

I will receive a set of (X/Y) array values in real time(100 elements per each set) continuosly. I want to plot that in X/Y graph when I receive each 100 elements (this 100 elements will be received as a set), but when I plot the new set I want to retain the old set of information in the graph. So every time when I receive a set of values one plot is increasing in same graph (consider that I'm not receiving all the set simultaneously, I will receive it one by one)

Could you please anybody help me to develop a subvi

Best Regards,

Use shift registers and a Build Array for the x and y data or use (ugh), the Express XY Graph. It retains old data if you don't set the reset to be true.

Yap. But is it possible to give  a sample VI?

Thank you,

Why don't you try to write something yourself first? Shift registers are basic LabVIEW knowledge. The Express XY Graph doesn't even require any coding.

And Express VI's are carnal LabVIEW knowledge.

This is a duplicate post.

To Poster: Your question is answered by looking at the examples that ship with LabVIEW. Search the examples for "XY Chart".

Thank you very much Broken Arrow

That's what I expected

Dennis answered your question, I just made a screen shot and a sarcastic note about Express VI's. You'll never grow as a LV programmer if you use Express VI's where there exists a more direct and efficient programming method (which is about always). But I'm glad that your issue was resolved.
