xy chart buffer question...

[mia.lara]

Hello everyone,

I know that this has been asked before, but I search and search and still don´t know what I´m doing wrong. I have continously adquired data that I want to place in a xy graph... so I need a buffer. The example XY chart buffer vi is perfect, but my vi just graphs the points that I have designated in the history length control and then keeps running without graphing anything else (as you can see in the attached image). The example called Variable-time chart xy it´s exactly what I want, but the data in that vi it´s a cluster of 2 elements...I don´t know how to convert my data for the buffer vi can work properly. Any help will be very appreciated...

Thank you... have a nice day!! =D...

In the code snippet you showed you're always clearing the buffer (you have a True constant wired to the VI). In the examples you can see that the clearing is only done on the first iteration.

I don't understand this question. Is your data different than what you've shown in your small screenshot?

Hi, thanks for answering..

What I meant in that question is that I can't manage or convert my data so I can use the xy chart buffer VI like in the variable-time chart VI (new point input: cluster of 2 elements). I just thought that maybe it would be an alternative, as the other one didn't work (new points input: array of cluster of 2 elements)...

But you're right, in the examples only the first iteration is true... so I'll try that tomorrow....(I have all the VIs at other place... =S).

I'm sorry for this questions lol.. I'm new in LabVIEW, but it's no excuse: next time I'll try EVERYTHING before posting (I would have deleted this thread the second after I posted it but there's no going back, huh?)  =S

Thanks for everything... =D... Have a nice day....!!

There is no need to apologize. Everybody is new at something at some point in their lives (especially at the beginning!). Sometimes you can be too close to the problem. Please post back if you have further issues.
