Update

@Qrrbrbirlbel's answer is perfect, but when I try to replace the tikz with tikzpicture, but looks like not work as expected. the offset of each annotation line shift to left a little bit.

Only the edges need to be overlayed.

Instead of overlaying the whole diagram, we'll just let PGF/TikZ find the right horizontal position itself by setting trim left = 0pt. On the second compilation run, the green nodes will be placed correctly in relation to x = 0pt, i.e. the left side of the picture.

The vertical position of the green nodes is setup as if they would have been placed as normal TeX text in a new paragraph below the listing. This is done by a combination of baseline = 0pt and setting the y value of the node's base anchor to 0pt as well (this is the - part in the at specification).

The entries of the loop are setup so that \t specifies the content of the green nodes while \n specifies the number of the upper gray node while thet \ns macro should contain all other gray nodes below that. Leave it out (which makes it default to the same as \n) if there's only one gray node for that column. This is caught by the \ifx test.

The varwidth option of standalone makes it possible to actually use multiple paragraphs in the first place.

  • +1 Although I do not understand this. The nodes themselves are also referencing to be placed correctly and though needs overlay (to prevent the ever increasing size of the tikzpicture for every compile). As I can see, your solution only seems stable because of varwidth (I do fully understand this option). Is your solution truly stable from one compilation to the next?

  • @hpekristiansen standalone is a black box for me, but the manual says: “The resulting effect [of varwidth] is […] that multiple paragraphs can be included as part of the content.” The TikZ picture that places the green nodes is now on its own paragraph which is, of course, under the listing. The solution appears to be stable for varwidth/standalone as well as for article. The green nodes should not be overlayed because we want their size to matter.

  • The size ever increasing only happens because TikZ can't “reach” a coordinate from another diagram because something is in the way (that would happen, if we would reference the gray nodes without overlay (here it is in every edge). \tikz[remember picture]\draw (0,0) -- (current page.center);` in article works without problem because TikZ can enhance the bounding box to include current page.center.

  • Awesome, can we still keep tikzpicture environment?

    @hpekristiansen Yes and no. Of course, it is referenced but only the x part of it is used to find a point that is not occupied by something else. This is done by taking the vertical part of 0,0 and aligning it to the baseline of this TeX line (baseline=0pt). Why this also needs separatly 0,0 on the path may need some investigating (the x part of this is irrelevant as long as it is the same).

overlay TikZ pictures does not take up space. Here is a solution where vertical space is added manually at the end.
