How to export charts from excel to image file of selected resolution and file format?

[fishthinkers]

A student tried this and reported poor results, so I then also tried it and found that the “export with settings” produces large graphics, but in our test they look terrible if you zoom in. I read on the forums from a few years back that the toolbox lost the functionality to anti-alias them, so they now look jagged. Could that be the issue?
