When I print a front panel containing a graph (who ever does that?) I get a stunningly beautiful publication-quality render of my data (overlooking the poorly done vertical y-axis label). However, all the many options of directly exporting a graph image (detailed here) ultimately provide only a screen-resolution image. See the contrast in image quality below:
Printed front panel vs exported graph image.
This idea has been discussed ad infinitum on the forum (see, for example, here, here, here, here, and here), but has never been adequately resolved. (Enlarging the graph for export does not work since graph elements do not scale, so lines, points and labels end up being far too small.) High time to implement a feature that has been in demand since (at least) 2002!
