Hi this is a bit of a long shot but I'm curious as to whether it can be done. I'm creating a graph with gnuplot and outputting as postscript, is there a way to make the graph dynamic such that as you zoom in the numbers on the axis scale. i.e. zoomed out you see 0, 1, 2, 3, 4, 5. Zoomed in to a section sees 1.1, 1.2, 1.2, 1.3, 1.4, 1.5 . Cheers.
No - although a postscript file is actually a program in a full-fledged language, it has no information on zoom level when being rendered.
It is possible that some postscript implementations have a way for the postscript program to actually know the raster resolution is rendering too - and if that is true, it would be theoretically possible, but it would be non-trivial. Non-trivial as in: require a lot of coding in postscript itself, including dinamically generating the label's text - usually text in postscript files is "hard coded" in place at time of generation of the postscript file itself. It certainly would not just a quick hack prepended to the file
