Hello Shilei Tian! When you middle-mouse-button-click on a Qt GUI, you get a menu,
and that contains a "Save" entry. (You can definitely call that
same functionality programmatically, too, but I'd have to look up
how – I'd expect you'd have to send the right Qt signal to the
right Qt slot to trigger the action, or you can grab the same data
as that save function saves to disk). However, that won't have a better quality than the screenshot, normally – the image is rendered as pixels, not as vector graphics, normally. But you're on the right track: > some data that I can use to plot with Matlab If you want offline analysis, having something like the file sink might be the easiest approach.
