select plot by mouse in a multi-plot graph

[Osiris81]

Hello

I'm using LV 8.5 and have a question using a waveform graph. I have multiple plots (up to about 300) in this graph and most of them will have approximately the same waveform but some will have a totally different -> the user needs to identify these plots (get the name of it when moving the mouse over it for example).

Is there a possibility to identify a specific plot in a multiplot graph?

Thanks a lot for your answer!

If you have a single plot cursor there is a property of the graph called cursor plot. You can read that value...to move the cursor to a different plot you right click on it and click 'snap to' <plot name>, then the value updates to the new plot you selected with the cursor. There might be a smilar, but better way to do that, you should play around with it a bit and see what you can find.

Hello

Thanks for your answer!

Unfortunately, it does not help me because I need it exactly the other way. I want to click on a plot and get its name. When there are 300 plots, you can't just go through all of them by the cursor (snap to each).

Any other ideas?

Yeah I kind of figured...

I couldn't find any other way to do, but I will keep trying, let me know if you find something (so I can stop :P)

BOY oh boy! I can't seem to find anything to help you. Can't seem to get any useful information from the plots period, mostly just setting the values and styles (reading them back, but you have to specify the active plot first, and can't programically change that with a click event on the plot). I am gonna take a break from looking at this one and try with fresh eyes tomorrow.

Hello,

I still haven't found a solution to identify a plot in a multiplot graph. Does anyone has an idea how that could go, I'm sureley not the only one that needs that?

Cheers

I would suggest an alternative approach given all those graphs. I think a user will start playing the "hunt for the right pixel to click" game with so many traces. I would suggest having a dropdown to select which plot to highlight. See attached for a sample way of doing it (LabVIEW 8.2).

I have a graph that can plot up to 48 different waveforms on a graph. In generl, I only want to have a subset to be displayed. I created a boolean array to allow me to select the plots I want. Each time I select the plot, my VI redraw the graph and display or remove the plots. I assume you could do the same thing. If you have so many, you might want to have a cluster associated with the plot selection, where one item is the name of the plot and the other to display or not display the plot.

Hello and thanks for your answer!

Unfortunately this solution does not work, I add a picture to show the problem. If the user has to click through all plots (1500...) to get ther right one, he needs really a lot of time!
