Simulink Scope Screen Cursors Disabled

I have a Simulink file that refuses to show the measurement tools on the scope. Note how the the time/value boxes are greyed out. Also, the 'show panel' does not work. I have other Simulink files where this is working just fine. I tried to delete and insert the scope again, but that did not help. I can't find this mentioned anywhere in Help or Support. I can run the Screen cursors in another Simulink file in the same session, so it is something in this configuration.

Hi Carl,

I understand that the measurement tools in your Simulink Scope block are greyed out or disabled in one specific model, while they work as expected in others.

It sounds like the issue might be related to how data is being fed into the Scope block in your specific Simulink file. Here are a few things you can try:

1. Check if Data Exists: Measurement tools (like cursors and value boxes) are only enabled if the Scope has data. Make sure you have run the simulation and the Scope is connected to a signal that produces data.
2. Simulation Mode: Ensure you are running in "Normal" simulation mode. Some features may not be available in "Accelerator" or "Rapid Accelerator" mode.
3. Scope Configuration: Compare the Scope block settings with those in a working model, especially buffer size and data logging options.
4. Data Type/Dimensions: Measurement tools may not work if the input signal is an unsupported data type or dimension. Make sure it’s a standard numeric signal.
5. Clean Build: Try closing Simulink, clearing the workspace (clear all; close all;), and reopening your model.
6. Model File Issues: If the issue persists, try copying your model contents into a new file, or gradually disabling/enabling blocks to isolate the problem.

I hope this was helpful.
