TeX - LaTeX Asked on July 11, 2021
Is it possible to scale a tikz
figure to the maximum size possible for the page with the text that is present on it using some parameters? For example, are there some parameters such that
usepackage{float}
usepackage{tikz, pgfplots}
begin{document}
begin{figure}[H]
begin{tikzpicture}[scale = **SOMETHING_HERE_TO_AUTO_SCALE_TO_MAX_SIZE_ON_PAGE?**]
% ... code to draw figure
end{tikzpicture}
end{figure}
end{document}
The only way I have been achieving this is by trial and error.
By this I mean I try
begin{figure}[H]
begin{tikzpicture}[scale = 1]
% ... code to draw figure
end{tikzpicture}
end{figure}
It fits on the page so can I make it bigger? Try
begin{figure}[H]
begin{tikzpicture}[scale = 2]
% ... code to draw figure
end{tikzpicture}
end{figure}
It’s too big, so I scale down
begin{figure}[H]
begin{tikzpicture}[scale = 1.5]
% ... code to draw figure
end{tikzpicture}
end{figure}
Ok it fits again. Can I make it bigger?
… etc.
Is there an easy way for latex to auto adjust the picture to the maximum size possible on the current page with all text, other figures etc. that are already present?
Inserted figure is "fixed" to some extent. So I do not use figure
environment or other float
environment.
The idea is simple: calculate the remaining height of the page
dimexprpagegoal-pagetotal-#1relax
#1 is the reserved space for center
environment and caption
, 4baselineskip
by default.
Then fit the tikzpicture
to the box of width textwidth
and height dimexprpagegoal-pagetotal-#1relax
.
getpicdimen
is used to get the original size of the pic.fittobox
is used to fit the pic to box of fixed width and height.fitremaining
is used to fit the pic to the remaining space of the page.documentclass{article}
usepackage{tikz}
usepackage{caption}
usepackage{showframe}
usepackage{lipsum}
usetikzlibrary{fit, calc, positioning}
usepackage{xparse}
renewcommand*ShowFrameColor{color{red}}
NewDocumentCommand { getpicdimen } { s O{picwidth} O{picheight} +m }
{
begin{pgfinterruptboundingbox}
begin{scope}[local bounding box=pic, opacity=0]
IfBooleanTF {#1}
{ node[inner sep=0pt, fit=(#4)] {}; }
{ #4 }
end{scope}
path ($(pic.north east)-(pic.south west)$);
end{pgfinterruptboundingbox}
pgfgetlastxy{#2}{#3}

Some other text.
