How do I zoom into a selected region in Simulation Data Inspector during a simulation in Simulink R2025b Update 2?

I have a simulation running in Simulink R2025b Update 2. In Simulation Data Inspector (SDI), when a simulation is running and I try to zoom in on a particular spot on a graph, it does not zoom into the selected region. It instead zooms into the time currently being simulated.

How can I zoom into a specific location while the simulation is running?

From MATLAB R2025a, the behaviour of the zoom functionality in SDI has changed, and the zoom area automatically "jumps" to the latest point. 

To zoom into older data points while the simulation is running, you can use the "Hold" button in SDI to pause the streaming. Pausing the streaming will not impact the simulation performance. You can then resume when you are done zooming into your selected region. 

The location of the "Hold" button is shown in the below image:
