I can't figure out how to align the following tree properly.
The tree itself is not centered within the page and the branches are not aligned vertically nor horizontally.
I'd like the nodes to be aligned on some sort of invisible grid, and the whole thing to be centered in one single page.
Edited for clarification:
- The pink circle shows that the tree should be centered.
- The green lines show that these boxes are not aligned horizontally.
- The blue lines area: these attempt to show the invisible grid along which the nodes should be aligned vertically. In other words, the space between the blue lines should be the same throughout. Right now, for instance, the 8th Level nodes are not aligned with each other. Moreover, the space between the 7th level node and the 8th Level nodes is not the same as the space between the 8th Level nodes and the 9th Level node. Ideally, all of these spaces should be the same throughout.
I've tried to adjust the space between the various Levels manually (by adding a centimeter here or 4.5 cm there), but it's not working

If you say e.g.
tier=l2for several nodes, then Forest will align those nodes (if possible). To centre the tree on the page, you have to do something outside theforestenvironment, such as using thecenterenvironment. However, space is at a premium, so I use\centeringhere to avoid the extra vertical space. I've also addedgeometrywhich defaults to slightly more sensible margins and reduced the separation andinner septo accommodate everything. I've usedfit=bandto make sure things don't overlap column-wise and some empty nodes to specify missing tiers. If you don't need to represent missing tiers spatially, you could remove some of these and put theinner sepback to4. You could also do this if your text height is larger thangeometry's default (or if you're using A4, say).I've added the
showframeoption to show the text block and margins etc. Obviously, you should remove this in your real document!
