GanttProject showing a century in timescale

I already have checked some ideas on laaarge timescale.

I am wondering if GP would be good tool to get some genealogy timelines with births and deaths. (decades).

How to get such a large timescale in few pages?

According to Dmitry’s response over here:

I think the answer is no, it won’t do that.

Pity. I’m looking for pretty much the same tool as you are, and GP looks like the best…if it would do that.
