An alternative to the high-resolution graphic export is the screenshot-quality export:
This is better suited for graphs that you want to use in digital media, e.g. in e-mails or presentations. One important difference between screenshot-quality export and high-resolution export is that the former produces ‘anti-aliased’ images where ragged lines are made smooth by interpolating with shades of gray (and other hues). The high-resolution export does not use anti-aliasing, so that text may appear ragged when zoomed in on screen. However, for printing on paper, this mode is preferable.
