绘制来自 LaTeX 表的数据

Question 1

有一种解决方案虽然不能完全满足您的要求，但在我看来，它非常优雅。

首先，将数据放入数据文件（文本文件）。在本例中，我将其命名为2014-01-01.txt。

freq    conc    lino
125     0.01    0.02
250     0.01    0.03
500     0.015   0.03
1000    0.02    0.03
2000    0.02    0.03
4000    0.02    0.02

接下来，使用pgf图生成图表，pgfplotstable生成表格，均从数据文件读取

\documentclass{article}

\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepackage{booktabs}
\usepackage{array}
\usepackage{colortbl}

\pgfplotstableset{% global config, for example in the preamble
  every head row/.style={before row=\toprule,after row=\midrule},
  every last row/.style={after row=\bottomrule},
  fixed,precision=2,
}

\begin{document}

\pgfplotstabletypeset[
  columns/freq/.style={column name=Frequency (Hz)},
  columns/conc/.style={column name=Concrete},
  columns/lino/.style={column name=Linoleum},
]{2014-01-01.txt}

\begin{figure}[h!]
\centering
\begin{tikzpicture}
\begin{axis}[
    xlabel={Frequency (Hz)},
    ylabel=Absorption Coefficient,
    legend pos=south east,
    legend entries={Concrete,Linoleum},
    ]
  \addplot table [x=freq,y=conc] {2014-01-01.txt};
  \addplot table [x=freq,y=lino] {2014-01-01.txt};
\end{axis}
\end{tikzpicture}
\end{figure}

\end{document}

输出：

已编辑

现在数据文件被转置，以便每一行对应一种材料。

freq    125 250 500 1000    2000    4000
conc    0.01    0.01    0.015   0.02    0.02    0.02
lino    0.02    0.03    0.03    0.03    0.03    0.02

除了我们需要转置 pgfplotstable 对象外，代码类似。

\documentclass{article}

\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepackage{booktabs}
\usepackage{array}
\usepackage{colortbl}

\pgfplotstableset{% global config, for example in the preamble
  every head row/.style={before row=\toprule,after row=\midrule},
  every last row/.style={after row=\bottomrule},
  fixed,precision=2,
}

\begin{document}    

\pgfplotstableread{2014-01-01-transpose.txt}\loadedtable
\pgfplotstabletranspose[colnames from={freq}]{\transposetable}{\loadedtable}

\pgfplotstabletypeset[string type]\loadedtable

\begin{figure}[h!]
\centering
\begin{tikzpicture}
\begin{axis}[
    xlabel={Frequency (Hz)},
    ylabel=Absorption Coefficient,
    legend pos=south east,
    legend entries={Concrete,Linoleum},
    ]
  \addplot table [x=colnames,y=conc] {\transposetable};
  \addplot table [x=colnames,y=lino] {\transposetable};
\end{axis}
\end{tikzpicture}
\end{figure}
