Feature request: Zooming out to Quarter/Year timeline

GanttProject Desktop Support
1

Hello,
unfortunately I created the gantt chart for my research proposal in ganttproject and have only now realized, that you cant zoom out to more then a monthly view. This makes it impossible to display a 5 year plan meaningfully on a dinA4 page. Hitting up google found people more then a decade back with the same problem. Please think about adding it, the lack of this feature meant for me, that i had to start over with a different tool.

There is also an open issue for this

edit: I should also add, that this especially frustrating as ganttproject is often the first project to be mentioned when looking for gantt on Linux. The lack of such a basic feature made me curse myself for not using the Microsoft version.
cheers

Same issue here.
I would like to plan a program with 4 year view. Maximun is 2 year, with current zoom setttings.
Any suggestion, please?

Happy new year 2022!!!
Would it be possible to estimate this feature?
I do not see very expensive to implement… is it?
It would be great for multi-year initiatives.
Thank you!

Hey I got both of you beat! Diagramming the genealogy in Genesis 5, per the text:

How’s that for zooming out?

(and the need for an arbitrary year, not connected to anything modern: one workaround is to offset everything so that nothing comes before the year 1000, and then remember that offset…)

For the obvious question of, “Why not use days to represent years, since the text is only that precise anyway?”, I’m including other things that are specified in days, and I want to show the actual relative sizes of both, if the text is taken literally.

If there’s another free, offline tool that works better for this, please let me know!

Or remove the restriction from this one. I imagine that beyond the present zoom level, the week highlights would disappear, possibly replaced with months, years, decades, centuries, etc. And what to do about tasks that become smaller than 1 pixel? So it’s not quite as trivial as just removing an “arbitrary” limit. Some logic and display elements would have to be added too. But I would still appreciate if that were done.

One possibly easy way to do it might be to show all of those marks, according to some user options to reduce clutter, with longer intervals taking priority, and simply “disappear” (don’t draw) anything that is less than 2 pixels at the current zoom level. For this purpose, the periodic time intervals (weeks, months, years, etc.) would be considered to be as wide as the time that they represent, and drawn as a single pixel followed by transparency for the remaining width. When the transparency becomes less than 1 pixel (the entire object less than 2 pixels), the object disappears.

Thanks!
