I hope, this question has not been asked on the site before. I recently did the following codes to make two plots separeately. I am thnking of if we could make to plots next to each other while they are being executed? I found this link through the site but, it is related to the case of images not fresh plots.
\documentclass{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{fillbetween}
\pgfplotsset{width=7cm,compat=1.15,
every axis legend/.append style={at={(0.5,-0.1)},anchor=north ,draw=none}}
\begin{document}
\begin{tikzpicture}
\def\verticalbar{2}
\begin{axis}[domain=-0.5:4.5,
grid=major,
legend columns=4,
samples=25,
smooth,
width=7cm, height=7cm,
axis lines = middle,
xlabel = $x$, ylabel = {$y$},
xtick={-2,...,8}];
\addplot [name path=A, thick, blue,dashed,domain=0:4.5] {4*x-x^2};
\addlegendentry{$f=4x-x^2$}
\addplot [name path=B,ultra thick, red] {7-x};
\addlegendentry{$g=7-x$}
\draw [name path=C, dotted, thick] (1,0) -- (1,6);
\draw [name path=D, dashed, thick] (4,0) -- (4,4);
\addplot [gray!40] fill between [
of=A and B, soft clip={domain=1:4},];
\end{axis}
\end{tikzpicture}
\end{document}
I mean our output being as follows:
groupplot, see for example https://tex.stackexchange.com/questions/349599/two-barcharts-next-to-each-other-with-different-widths-and-same-height/349605#349605 Or you can put multipleaxisenvironments in the sametikzpicture, and position the second one with theatkey, see for example https://tex.stackexchange.com/questions/289079/2x2-array-of-pgf-plots/289087#289087 – Torbjørn T.
