I am trying to do a History timeline .. from , well, the beguining of civilization to current times.
The idea is to have a overview of big civilization events and trends and then be able to zoom in into the events that mark the centuries , and then zoom in to specific years, events , battles, people etc..
so far this is 1st draft...

So I would need a grid that ideally “auto-resize” the dates. But anyway of creating a grid with 4000 columns for years woulkd also work.
This sort of timeline would be great for history ( i am doing it for my children..) but also for any kind of organization .. key events etc..
I can also see the use for a personal timeline, calendar , planning , .. where you have like the big Yearly objetives , then break them Quarterly objectives , Monthy -weekly planning and even the Daily to do in a visual way , grouped by interelated projects etc..
Any ideas , suggestions .. ?
Let me now
Also posted as question in case any suggestion on how to do it / workaround
