Is there any built-in way in the tikz package for moving/positioning a whole set of paths and nodes relative to another set or to the document's page?

To illustrate what I mean, here is what I was working on:

As you can see, I placed a distinct drawing next to another one. But I think the way I achieved it isn't the simplest/most elegant solution: I've used a tabular.

\end{minipage}

Also, in each tikzpicture I had to define the same coodinates (A), (B), (C) and (D).

Is there a better way to do this, within the same tikzpicture?

It may seem relatively trivial and unnecessary to search for an alternative solution in this case, but this is just because the intended positioning is simple here: two drawings, one next to the other. But imagine we had to place three, four images, and had to position them in a special way—each image in the vertex of a regular polygon, for example.

Edit: Preamble for compiling code

I put in all of the packages used in my document so I don't have to find out, by tedious trial-and-error, what's the minimal set for compiling the code above.

    Are you aware of the subfig package or any related package? – user121799 Mar 24 '18 at 22:14
  • As for your second question, you could store the common parts of the TikZ pictures in some macro which you re-use and then you'd only have to worry about the new parts. This will allow you to make global changes more easily. – user121799 Mar 24 '18 at 23:06
  • use subcaption instead of subfig – percusse Mar 24 '18 at 23:20

    subcaption (or the older subfig) is really only useful if you want numbered captions for each subfigure. If you don't want that they are completely pointless. – Torbjørn T. Mar 25 '18 at 16:20

    Yes, in this case it doesn't seem to be the right solution for you. That's why I did not put this in my solution. However it is quite powerful when dealing with multiple axis environments. – BambOo Mar 26 '18 at 9:26

EDIT n°2 : as it is not recommended to nest tikzpictures, you may use scope environments instead. I update the second snippet accordingly.

A first answer with the subcaption package as advised by @percusse. I had to remove some fetaures of your snipppet to make it compilable, bu you have the idea of what to do.

EDIT : if you really need to position them in a weird fashion, you can nest your tikzpictures inside some nodes and position them relativley to one another. I don't know if it is useful in you case or even recommended, but it might help.

  • Please don't encourage nesting of tikzpictures, it can often cause problems, and is also completely unnecessary in this case. – Torbjørn T. Mar 25 '18 at 16:22
  • As I mentioned in my first edit, I was not sure about this. I guess using scope environments is more TiKzy right ? – BambOo Mar 25 '18 at 20:22
  • Thanks! I think you forgot the \begin{tikzpicture}[scale=3] before the first \begin{scope}[], though. – Anakhand Mar 26 '18 at 9:05
  • Yes you are absolutely right, i will correct it promptly. – BambOo Mar 26 '18 at 9:23
  • Could I ask you to put your Edit nº2 section uptop, so that it is the first thing to be read from your answer? It's the part that best suits the intention of this question – Anakhand Mar 26 '18 at 22:18

  • for base of your images i use code from my answer on your previous question
  • to make the code for complete figure shorter i define new command which contain common part of both images
  • images are positioned by \centering and \hfil between them:

  • Thanks again! Just one little thing: in the second figure, the green angle is smaller than in the first figure, so we would have to put the respective commands out of the common \ANGLES command. – Anakhand Mar 26 '18 at 9:00
  • By the way, great improvement on using the \path (E) arc (90:60:1cm) node[midway,sloped,font=\footnotesize] {$\|$}; expression to add the double lines on the arcs; I didn't know about it, thanks – Anakhand Mar 26 '18 at 10:42
  • Very nice. zARKO...+1. – Sebastiano Mar 26 '18 at 20:51

You don't need a table, you can place the two tikzpictures next to each other like any other letter:

(As your code did not compile even after adding the obvious missing packages, I used the code from https://tex.stackexchange.com/a/423061/36296)
