Advanced Graphing problem

[Albert Chan]

I've had similar issue, but I thought it was because I use old (2018) HP Prime emulator.

Is there a simple way to zoom-in, with X = [0,8], Y = [40,60] ?

Zoom-Box option does not allow directly entering corner coordinates.
It only allow point and click for corners, but does not show coordinates.
We don't even know where the corners are without zoom-out, many times.
