Unable to zoom graph

[Yuhoi]

I recently swamped from Garmin Fenix 6 to Suunto Ocean so I’m new to the app. I’m trying to zoom in the speed graph, however, it doesn’t indicate the zoomed range like this graph from Suunto Race shown below:

This graph below is what my app shows.

Is there a setting I need to change to something else? Any input is appreciated.
