我在一些工作上遇到了麻烦,如果能得到帮助我将非常感激。我想将这种文本添加到我的项目中:
这是我的代码,我不知道为什么node[left]{$P^*=50$}
没有node[below]{$Q^*=500$}
显示
\begin{tikzpicture}
\begin{axis} [axis lines = left, xlabel = $Q$, ylabel = {$P$}]
\addplot [domain=0:960, samples=100, color=green] {0.1*x} node [left] {$CMg$};
\addlegendentry{$0,1\cdot Q$};
\addplot [domain=0:1000, samples=100, color=red] {100-1/10*x} node [above right] {$IMg$};
\addlegendentry{$100-0,1\cdot Q$}
\draw [dashed] (0,50) node[left]{$P^*=50$} -- (500,50) -- (500,0) node[below]{$Q^*=500$};
\end{axis}
\end{tikzpicture}
提前致谢!

让我阐明我的评论...并对图表代码进行一些小修改。您可能喜欢它:
\documentclass[margin=3mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
axis lines = center,
xmax=1150, ymax=110,
xlabel = $Q$,
ylabel = $P$,
label style=right,
legend style={at={(0.5,1)},legend columns=-1,
font=\scriptsize, anchor=north},
legend cell align=left,
samples=2, no marks,

\addplot +[domain=0:960] {0.1*x} node [right] {$CMg$};
\addplot +[domain=0:1000] {100-1/10*x} node [above right] {$IMg$};
\legend{${100-0,1{\cdot}Q}$, ${0,1{\cdot}Q}$};
\draw[dashed] (-2pt, 50) node[left, font=\footnotesize]{$P^*{=}50$} -|
