Is it possible to toggle visibility of signals in (floating) scope during simulation?

2 views (last 30 days)
I am looking for a way to connect multiple signals to a Simulink scope (can be a floating scope as well) and dynamically toggle the visibility of lines (individual signals) during a simulation. The toggling could for example be handled in a callback function, a Matlab function block, or a StateFlow action. Is there a way to (programmatically) achieve this? Important is that it needs to work during a simulation.

I tried a simple test to check if setting scope configuration in runtime is possible or not: 1. Open shipped demo 'vdp'
>> vdp
2. Set the end time to Inf and run the model
3. In MATLAB command window, I can change the scope configuration during simulation. In this case, by changing 'Visibility' property, I can open or close the scope.
>> myScopeConfiguration = get_param('vdp/Scope','ScopeConfiguration')
>> myScopeConfiguration.Visible = true
If you are able to dynamically toggle the visibility of lines with callback function or MATLAB function block, you should be able to perform this workflow with command line functions. Good luck!

Thank you for the answer. I think my question was not clear enough. I do not want to toggle the scope visibility. The goal is to toggle which of the input signals is shown on the scope. I could not find in the documentation if this is possible. Any ideas?

I was not able to find information on how to toggle which input signals are shown on the scope programmatically. I will create an enhancement request for the development team to consider this feature in future release.
