General ⇒ Forest horizontal node alignement

[cyanidebaby]

Hello,

There are three, sharp-cornered, rectangular boxes at the top of the "forest table" which code I've pasted under. Let's call them the "Branch boxes".

The blank spaces between these "branch boxes" is not even, horizontally.
How do I make these spaces even?

Thank you.

Hello,

that's for symmetry: if you would make the spaces even, the whole branches would have a different distance to the middle. I thing an overall asymmetry is more bad than a single internal distance.

But there's another solution other than to change the spacing itself: make the width of the boxes equal, such as

Code: Select all

[\textbf{Green Branch},rounded corners=0pt,minimum width=4cm
...
[\textbf{Ecclesiastical Branch},rectangle,minimum width=4cm,
...
[\textbf{Military Branch},rectangle,minimum width=4cm
...

Just choose the minimum width so that the widest text fits. It can be automatically measured though, such as by using \settowidth. For repeating things, such as rectangle style with the same width, I would introduce a style.

Thanks very much, Stefan.
That works.

I guess I'm just going to have to figure out which look I prefer!

Thanks again.
