TikZ 数据可视化和尺寸太大

Question

我正在尝试使用 tikz 数据可视化绘制一个简单的图形，但遇到了“尺寸太大”。

\documentclass[a4paper,10pt]{book}

\usepackage{tikz}
\usetikzlibrary{datavisualization.formats.functions}

\begin{document}
 
     \tikz \datavisualization [scientific axes=clean, visualize as smooth line]
       data [format=function] {
         var x : interval [1338:5500] samples 100;
         func y =  (1000000 / \value{x} - 28 - 137.4) * 64 * 1.25;
       };

\end{document}

关于如何修复此问题我有什么想法吗？

Answer 1

逐字复制自 tex.stackexchange.com/a/518311。

\documentclass[tikz,border=2mm]{standalone}
\usetikzlibrary{datavisualization.formats.functions}
\newcommand{\pgfmathparseFPU}[1]{\begingroup%
\pgfkeys{/pgf/fpu,/pgf/fpu/output format=fixed}%
\pgfmathparse{#1}%
\pgfmathsmuggle\pgfmathresult\endgroup}
\begin{document}
\begin{tikzpicture}
    \datavisualization [scientific axes=clean, visualize as smooth line,
    /pgf/data/evaluator=\pgfmathparseFPU]
data [format=function] {
  var x : interval [1338:5500] samples 100;
  func y =  (1000000 / \value{x} - 28 - 137.4) * 64 * 1.25;
};
\end{tikzpicture}
\end{document}

这是另一种选择pgfplots

\documentclass[a4paper]{article}

\usepackage{pgfplots}
\begin{document}
    \begin{tikzpicture}
        \begin{axis}[
                domain =1338:5000,
                samples=100,
            ]
        \addplot[smooth] {1000000 / x - 28 - 137.4) * 64 * 1.25};
        \end{axis}
    \end{tikzpicture}
\end{document}
