I have a program where I need to display several data from multiple DAQmx channels in separate graphs. Putting a graph in a cluster in an array works, but you cannot separately modify axes for example. Because I know beforehand how many graphs I have, I've building upon the work done by user "tst" in this post: https://forums.ni.com/t5/LabVIEW/User-interface-problem-list-of-clusters/m-p/2311770#M726599. Basically, you create a VI with multiple subpanels, and have the graph in a separate VI which you load one by one into the subpanels. They use the 'Run VI' method to start, which doesn't allow you to input data to the VI.This works well for their case, but I need to communicate data to subVIs. I want to do this with a message queue. I create a separate queue for each instance of the graph VI and send the data to the corresponding queue when I need to. The problem I have is regarding cloning the VI instances. Please see the attached LabVIEW project for my efforts so far. Running the VIs asynchronously using the 0x80 option allows me to run the graph VI in the subpanels. Then using the queue I'm able to send the data to these VIs. However this load the same VI into the different subpanels, so this doesn't work well. For this I've added the 0x40 option (according to this reference), this should make a clone of the VI when I call it, but now the data is not being sent anymore and I can't figure out why. Can someone take a look at my program and understand why I have this problem?

Sorry if bumping and old topic is not allowed, but I've finally gotten around to investigated this problem again. As suggested, I've abandoned the idea of creating my own framework and starting learning about the NI Actor Framework. I've created the attached example that does exactly what I need. Even though the Actor Framework may be a little overkill for this particular case, I'm happy that it's modular and in the future it'll be easy to add additional features. Feel free to make suggestions or correction to this basic code, I've just started learning about the Actor Framework 😉

Emulate array of graphs using multiple subpanels

Solved!

At least re bumping topics, I think the record is somewhere around 19 years, and there are good examples of completely irrelevant posts more than 15 years later... So for something on topic, I wouldn't worry!

Good luck with the Actor Framework 🙂
