I am running Matlab 2019a on Ubuntu 18.04.2.
I am simply trying to zoom into an ordinary figure, such as one produced by plotting random numbers:
When I run the script, the figure pops up.
I can select the zoom tool.
However, when I attempt to drag the zoom tool to create a bounding box, no box forms. And thus no zoom occurs. I am also unable to use the pan tool. However, the 'data tips' and 'data brush' tools work.
This has occured recently, I am not sure what has changed in my setup to have caused this.
I previously has Matlab 2018b, but the zoom has also spontaneously stopped to work. So I upgraded to Matlab 2019a. But the zoom still does not work.
As a result, I suspect there is something related to the underlying system that is causing this. I know this is not related to OS version, as zoom worked before on this same OS. Any ideas?
