Multiple XY Graphs outside case structure

[ClausDK]

Hi LabVIEW Experts!

I'm having trouble trying to combine 4 XY Graphs into one. I have a case structure, which generate/update the 4 graphs sequentially. I need to do it this way, because I am multiplexing between 4 signals. No matter how I try to combine the plots into a single graph, the result is that only one graph is plotted. The screenshot below shows a simplified version of my currently working program which consists of a while loop that cycles between 4 cases (and plots each data set in a separate XY Graph):




In my "real" program I am of course not plotting random Y-values (I'm sampling data via GPIB from a frequency counter). The Time Delay is set to 1 sec, so each graph is only updated every 4 seconds. Is it possible at all to combine 4 XY Graphs that are not updated simultaneously into one single XY Graph? If so, I would be very glad if someone could point me in the right direction on how to do this.

Thanks in advance,
Claus Nielsen

Hi Claus,

What you want to do, is to merge those 4 XY-plots into one XY-graph. It may look somthing like the attached image.

Sorry I havn't done it with XY-Graph, but you should be able to do this with XY-Graph as well.

Cheers!
