XY Graph Multiplot Help

[Dennis_Knutson]

I think this is what you are looking for.

OK, so it appears that it's REALLY necessary to be able to duplicate the scale and create one for each plot.  Without it, I can NOT set the Active Y scale.  In my real program, since there is only one scale, I can only set Active Y Scale to zero (any other value returns error 1077).

So what could cause the original program NOT to be able to swap sides (duplicate works).

in your for loop use a shift register instead of the local variable.

Without seeing the original VI, I can not know what was wrong. As I mentioned, it could have gotten corrupted.

Can you please post the fix?  Remember, I'm VERY new to LabView.

[Dennis_Knutson]

I don't know what fix you are talking about. The VI I posted has a shift register to create an array of XY waveforms. Try using that as a model and see how far you get.

Okay, how's this now?  It works but would like to make sure I'm not doing any other less efficient/stupid things (like the shift register).  Also, the order of the members of the property node is important.

Hi mimyanky,

Your VI looks good.  The one suggestion that I have is to place those property nodes outside of the while loop.  Since you are setting the same value to them every time, you don't need to call them on every iteration of the while loop, as this would slow down your program.  Place them outside of your while loop, and wire up the error wires to the border of the while loop so that you will ensure that these are executed before the while loop.

Happy programming!

Marti...thanks but they're in there because in the real application, they're set dynamically w/ differrent values (I tried to make the example as close as possible to the original).

BTW, my application now works w/ no flickering and the overlays look great.  With communicating w/ the PNA-X and displaying multiple plots, I'm only less than 1/2 second behind the VNA.

Thanks for all the help.
