我有一个身影Plot1.tex我有一个用 matlab2tikz 生成的（Nico Schlömer 的 matlab2tikz）。我想将其包含在我的文档中并像这样缩放其宽度和高度：
\documentclass[a4paper]{report}
\usepackage{graphicx}
\usepackage{pgfplots}
% Recommended settings according to matlab2tikz:
\pgfplotsset{compat=newest}
\pgfplotsset{plot coordinates/math parser=false}
\newlength\figureheight
\newlength\figurewidth
\begin{document}
\begin{figure}[ht]
\centering
\setlength\figureheight{7.0cm}
\setlength\figurewidth{5.0cm}
\input{Plot1.tex}
\caption{Figure 1 caption.}
\label{fig:fig1}
\end{figure}
\end{document}
但是，图形大小不受我以厘米为单位指定的值的影响。请告诉我我做错了什么。包括\textwidth代替固定长度的解决方案也值得赞赏。我也试过了，但也没成功。
编辑：文件的内容Plot1.tex如下所示。

使用 ˙pgfplots 规定图表大小假设您的图像Plot1.tex是使用pgfplots包绘制的，并且没有在本地定义图像大小，那么您可以通过插入来定义图像大小
\pgfplotsset{height=5.0cm,width=7.0cm}
前\input{Plot1.tex}。
如果您使用standalone文档文件名绘制此图像Plot1.tex，它将帮助您获得以下 MWE：
\documentclass[a4paper]{report}
\usepackage{standalone} % <---
\usepackage{pgfplots}
% Recommended settings according to matlab2tikz:
\pgfplotsset{compat=1.16,
plot coordinates/math parser=false}
% \newlength\figureheight % not needed
% \newlength\figurewidth % not needed
\begin{document}
\begin{figure}[ht]
\centering
\pgfplotsset{height=5.0cm,width=7.0cm} % <---
\input{Plot1.tex}
\caption{Figure 1 caption.}
\label{fig:fig1}
\end{figure}
\end{document}
其中文件Plot1.tex必须修改如下：
%%%% Plot1.tex
%---------------------------------------------------------------%
\definecolor{mycolor1}{rgb}{0.00000,0.44700,0.74100}%
\definecolor{mycolor2}{rgb}{0.85000,0.32500,0.09800}%
%
\begin{tikzpicture}
\begin{axis}[%
%width=4.521in, % <--- remove
%height=3.566in, % <--- remove
%at={(0.758in,0.481in)}, % <--- remove, it has no sense
scale only axis,
bar width=0.8,

\addplot[forget plot, color=white!15!black] table[row sep=crcr] {%

现在主文件给出以下结果：
现在出现一个问题：由于您需要编辑所有这些文件，用所需的值（如果它们不同）替换 Matlab 确定的图表尺寸（高度、宽度）不是更简单吗？
