Resetting a ZedGraph plot

[ZegCricket]

Hello! I hope you are doing well.

I'm starting to use the GUI package for my project and I need to plot some data in real-time, but I need to reset the plots at the beginning of every block without having to close and reopen the GUI visualizer. Is there currently a way to do that?

Thank you in advance for the help!

As far as I know, there's no easier way in the editor (say a keyboard shortcut) that would reset the visualizer, but there is a way to achieve that in Bonsai workflows like in the first example here. Does that work for you?

Thank you for the reply! I hadn't thought about this solution, but unfortunately it doesn't work for me, because I would like to integrate the plot in a TableLayoutPanel, which doesn't seem to work just yet.

For the majority of my plots (although not for every single one), I was planning on just use the Capacity and/or Span properties, but they don't seem to work for the GraphPanel node. I used this example as a starting point to test this.

Thank you for the reply! When you said pull-request, I'm assuming you meant to open an issue (I think I probably will at some point).

1. The example in specific works, but if I want to propagate that reset of the plot to a complete GUI (with buttons, labels, other plots) I don't know how, because you would have to branch out the take and repeat part, since the Repeat node doesn't have the plot visualizer, which doesn't seem to work.
2. That's a nice suggestion, thanks!
3. For some reason, I can't make this example to work. It's simple and it seems that you got it working, so I don't know what's happening :/

I meant a pull-request where one could add more examples to documentation of the package

1. Cant you do the same as I did in the second example and use the repeat to resubscribe to the full UI? Can you attach a minimal example?
   For 3, can you try this?

Got it! I'll try to do it at some point.

1. You can, but I think it only works for that case where you want to reset the full UI. If, for example, you have a UI with 2 plots and you only want to reset one of the them and preserve the other, I think you're going to face the issue I was describing.

For 3, it worked, thanks! I forgot to configure the IndexSelector and the ValueSelector properties.

[bruno-f-cruz]

Yes in that case I don't see a solution with the current package. Def something to consider for future versions!

[ZegCricket]

Yes, it would be very cool!

And thank you so much for all of this back-and-forth conversation, it was really helpful, I think I'll use some of the tips you gave me in my project! :)
