Size of subfigure fitting its content (tikzpicture)












2















How can I set the width of a subfigure to fit its content, i. e. a tikzpicture.



In my MWE I do not want to specify 0.1textwidth respectively 0.9textwidth, but instead I want the whitespace to be distributed equally around both subfigures.



documentclass{article}
usepackage{showframe}
usepackage{tikz}
usepackage{subcaption}

begin{document}

begin{figure}[ht]
hfill
begin{subfigure}[b]{0.1textwidth}
centering
begin{tikzpicture}
node[draw] (pd1) {a};
end{tikzpicture}
caption{}
end{subfigure}%
hfill
begin{subfigure}[b]{0.9textwidth}
centering
begin{tikzpicture}
node[draw] (b) at (0,0) {b};
node[draw] (c) at (5,0) {c};

draw (b) to (c);
end{tikzpicture}
caption{}
end{subfigure}%
hfill
caption{}
end{figure}

end{document}


I found this answer How can I access the size of a tikzpicture's bounding box outside the tikzpicture? but didn't read it in detail until now. I was wondering if my aim could be achieved easier.

          You could place the tikzpicture in a savebox and measure its size. This size can then be used for the subfigure. The following example shows how to do this for the right hand image. In the same way you could create another box for the other image.



          documentclass{article}
          usepackage{showframe}
          usepackage{tikz}

          newsavebox{mybox}
          newlength{mylength}

          begin{document}

          savebox{mybox}{begin{tikzpicture}
          node[draw] (b) at (0,0) {b};
          node[draw] (c) at (5,0) {c};

          draw (b) to (c);
          end{tikzpicture}}

          settowidth{mylength}{usebox{mybox}}

          begin{figure}[ht]
          hfill
          begin{subfigure}[b]{0.1textwidth}
          centering
          begin{tikzpicture}

          • Maybe you should add something after the last hfill, e.g. hfillvphantom{x} to move the right figure away from the right page border?

          I think that @samcarter's nice proposal is the way to go. This is only if you need to access the nodes later (with remember picture), in which case saveboxes may be inconvenient. This proposal measures the widths of the tikzpictures and writes them to the aux files such that they get used in the next run. Conceptually it is the same as e.g. this nice answer.
