How to plot simulation results in a GUI while the simulation is running?

I need to plot the simulation results in a GUI while simulation is running, so that the plot will be updated whenever the simulation results are updated.I have tried using To Workspace block and To File block, both outputs the results to workspace or file only when the simulation is paused or stopped. I cannot pause the simulation neither wait for the simulation to stop just for updating the GUI. Is there any way by which I could plot the simulation result in live on the GUI?
When I am trying to access engineTorque value when the simulation is running, it says variable not found. When I pause the simulation I am able to accesss the engineTorque.But my requirement is to access engineTorque value(time,data) when the simulation is running.
NOTE:
1. The GUI can be opened in another MATLAB instance also.
2. Simulation is started with Sim command.
3. It will be helpful if solutions are specific to R2021a.

This approach gives you quick and easy access of the run-time data. I don't think there is any more APIs. You might consider the run-time objects in the first link, or search for SDI (Simulink Data Inspector).

Use drawnow command for updating the simulation results
