Non scalable unit in tikz












9














Is there a non scalable unit in tikz?



I have the following picture,



    documentclass{report}

    usepackage{tikz}

    begin{document}

    begin{tikzpicture}[>=latex, scale=2]

    draw[->] (0,0) -- (2,1);

    filldraw   (0,0) circle[radius=0.05cm] node[anchor=north] {$P$}

                (2,1) circle[radius=0.05cm] node[anchor=north] {$Q$};

    end{tikzpicture}

    end{document}


Some elements, like the line width, the arrowheads or the text aren't affected by the scale=2 option. I would like the circles to behave in the same fashion. Is this possible? I tried using different units for the circle radius (cm, pt, em) but I had no luck.

          You could use a node instead of a circle. nodes don't scale either:



           documentclass{report}
          
    usepackage{tikz}
          
    begin{document}
          
    begin{tikzpicture}[>=latex, scale=2]
          
    draw[->] (0,0) -- (2,1);
          
    filldraw   (0,0) node[circle,inner sep=0.025cm,fill=black]{} node[anchor=north] {$P$}
          
                (2,1) circle[radius=0.05cm] node[anchor=north] {$Q$};
          
    end{tikzpicture}
          
    end{document}

          Yes, scale really scales mainly distances, not line widths etc. UPDATE: I misread the question, sorry, and big thanks to Paul Paulsen for pointing this out. You can just divide out the scale factor in the circle radii.



          documentclass{report}
          
usepackage{tikz}
          
begin{document}
          
begin{tikzpicture}[>=latex, scale=2]
          
pgfgettransformentries{myscale}{tmp}{tmp}{tmp}{tmp}{tmp}
          
draw[->] (0,0) -- (2,1);
          
filldraw   (0,0) circle[radius=0.05cm/myscale] node[anchor=north] {$P$}
          
            (2,1) circle[radius=0.05cm/myscale] node[anchor=north] {$Q$};
          
end{tikzpicture}
          
begin{tikzpicture}[>=latex]
          
draw[->] (0,0) -- (2,1);
          
filldraw   (0,0) circle[radius=0.05cm] node[anchor=north] {$P$}
          
            (2,1) circle[radius=0.05cm] node[anchor=north] {$Q$};
          
end{tikzpicture}
          
end{document}


          enter image description here



          ORIGINAL ANSWER: Here I address how one can scale the line width with the distances. Note that I do not recommend using pgflowlevelsynccm here as it screws up the bounding box (which is why there are vspaces added), but I list it for completeness.

end{tikzpicture}
          

          
end{document}


          enter image description here



          And I would draw the thing probably like this:



          documentclass[tikz,border=3.14mm]{standalone}
          
begin{document}
          
begin{tikzpicture}[>=latex, scale=2,bullet/.style={transform shape,inner
          
sep=0.05cm,fill,circle}]
          
pgfgettransformentries{myscale}{tmp}{tmp}{tmp}{tmp}{tmp}
          
draw[->,shorten >=2pt,line width=myscale*pgflinewidth] 
          
(0,0) node[bullet,label=below:$P$]{}
          
   --         (2,1) node[bullet,label=below:$Q$]{};
          
end{tikzpicture}
          

          
end{document}


          enter image description here

          • But the OP asks how to not scale the circles, not how to scale everything...

          • @PaulPaulsen Very good point! Thanks a lot! (I had the opposite problem, i.e. wanted to scale the line width, some time ago, and was thinking this was asked here. But no, you are absolutely right, and I was too sloppy.)

          • While having to write /myscale can be a hindrance if there are many nodes, it allows not to scale any shape, so it is useful.

          Is there any reason why you chose inner sep=0.025 and not 0 or any other number?

          Yes, scale really scales mainly distances, not line widths etc. UPDATE: I misread the question, sorry, and big thanks to Paul Paulsen for pointing this out. You can just divide out the scale factor in the circle radii.

          ORIGINAL ANSWER: Here I address how one can scale the line width with the distances. Note that I do not recommend using pgflowlevelsynccm here as it screws up the bounding box (which is why there are vspaces added), but I list it for completeness.

          Yes, scale really scales mainly distances, not line widths etc. UPDATE: I misread the question, sorry, and big thanks to Paul Paulsen for pointing this out. You can just divide out the scale factor in the circle radii.

          ORIGINAL ANSWER: Here I address how one can scale the line width with the distances. Note that I do not recommend using pgflowlevelsynccm here as it screws up the bounding box (which is why there are vspaces added), but I list it for completeness.

          And I would draw the thing probably like this:



          documentclass[tikz,border=3.14mm]{standalone}
          
begin{document}
          
begin{tikzpicture}[>=latex, scale=2,bullet/.style={transform shape,inner
          
sep=0.05cm,fill,circle}]
          
pgfgettransformentries{myscale}{tmp}{tmp}{tmp}{tmp}{tmp}
          
draw[->,shorten >=2pt,line width=myscale*pgflinewidth] 
          
(0,0) node[bullet,label=below:$P$]{}
          
   --         (2,1) node[bullet,label=below:$Q$]{};
          
end{tikzpicture}
          

          
end{document}

          • While having to write /myscale can be a hindrance if there are many nodes, it allows not to scale any shape, so it is useful.
