Hi all,
I use Simulink to run Simulations over long time-ranges (up to 1 year). Because the simulation run for up to 18 hours I use simulink scopes to monitor signals while the simulation is still running (e.g. to evaluate if newly programmed logics work as expected).
I realised that in R2025a the signals are no longer shown in full data resolution when zooming in during the simulation. Before I used R2023b and there the data was shown in full resolution.
Following example shows the difference between R2023b (expected behaviour) and R2025a:
R2023b:

R2025a:

Both images show the same time-range in the same scope of the same model during simulation.
In the scope settings under logging both "Limit dat points to last" and "Decimation" are disabled.
After the simulation is finished the signals in R2025a are also shown in full data resolution. The difference between the versions only appears during simulation.
Are there any possibilities to get the same behaviour during the simulation as in R2023b? As our simulations run for multiple hours it is important to have the possibility to evaluate the signals even before the simulations are finished.Hi all,
