Gantt chart zoom

Hi, I have a schedule that goes out over five years and can’t zoom out enough to display it all (either pdf or on screen). I need it to essentially display the quarter or even just year to get a full view of the timeline. Is there a way to do this? I can only seem to get out to months.

Thank you in advance!

Can’t suggest anything better than what you can get with zooming buttons, sorry. You can export to PNG and zoom using image viewer, but that will just zoom out the image and won’t change the timeline units.
