MATLAB-like Vertical/Horizontal Zoom for strictly Vertical/Horizontal Drag

In the MATLAB figure controls, the zoom button allows me to only zoom horizontally if the mouse is moved horizontally or vertically. This is nice to have so that I don't have to drag across the vertical/horizontal extent every time I want to go to a specific spot.

I'd greatly appreciate this feature here as I use this extension for virtually all of my notebook development and find myself wanting to do this frequently. Thanks!


Start by reproducing the zoom-button behavior in a notebook and compare it with the MATLAB figure controls described in the issue. Trace the ipympl zoom interaction to determine how horizontal versus vertical mouse movement is handled; done means a strictly horizontal or vertical drag zooms only that axis without affecting the other.
