如何在 tikz-pgf 中选择一系列数据？

Question

这是我想要用来创建堆积条形图的表格的子集：

是否可以选择前两行的 A 到 F 列，然后选择其他行的 G 列来创建堆积条形图？

这是我的 MWE：

\begin{tikzpicture}
\pgfplotstableread{ % Read the data into a table macro
Label A B C D E F G
Yes 0.24    0.92    0.52    0.96    0.52    0.24 nan
No 0.76 0.08    0.48    0.04    0.48    0.76 nan
High nan nan nan nan nan nan 0.08
Medium nan nan nan nan nan nan 0.4
Low nan nan nan nan nan nan 0.52
}\datatable

\pgfplotstabletranspose[string type, colnames from=Label, input colnames to=Label]\datatabletransposed{\datatable}

\begin{axis}[
    xbar stacked, % Stacked horizontal bars
    xmin=0, % Start x axis at 0
    ytick=data, % Use as many tick labels as y coordinates
    yticklabels from table={\datatabletransposed}{Label}, % Get the labels from the Label column of the \datatable
    legend style={at={(0,0)}, anchor=north east,at={(axis description cs:0,-0.1)}}]
]
\addplot [fill=green!70!blue] table [x=Yes, y expr=\coordindex] {\datatabletransposed};
\addplot [fill=red!70!white] table [x=No, y expr=\coordindex] {\datatabletransposed};
\legend{Yes, No}
\end{axis}
\end{tikzpicture}

对于缺失数据，使用 nan 或 NaN 不是一个好主意，至少对于堆积条形图来说是这样。

\documentclass[multi=tikzpicture]{standalone}
\usepackage{pgfplots,pgfplotstable}
\begin{document}


\pgfplotstableread{% Read the data into a table macro
Label A B C D E F G
Yes 0.24    0.92    0.52    0.96    0.52    0.24 0
No 0.76 0.08    0.48    0.04    0.48    0.76 0
High 0 0 0 0 0 0 0.08
Medium 0 0 0 0 0 0 0.4
Low 0 0 0 0 0 0 0.52
}\datatable

\pgfplotstabletranspose[string type, colnames from=Label, input colnames to=Label]\datatabletransposed{\datatable}

%\begin{tikzpicture}
%\node{\pgfplotstabletypeset[string type]\datatabletransposed};
%\end{tikzpicture}

\begin{tikzpicture}
\begin{axis}[
    xbar stacked, % Stacked horizontal bars
    xmin=0, % Start x axis at 0
    ytick=data, % Use as many tick labels as y coordinates
    yticklabels from table={\datatabletransposed}{Label}, % Get the labels from the Label column of the \datatable
    legend style={at={(0,0)}, anchor=north east,at={(axis description cs:0,-0.1)}}]
\addplot [fill=green!70!blue] table [x=Yes, y expr=\coordindex] {\datatabletransposed};
\addplot [fill=red!70!white] table [x=No, y expr=\coordindex] {\datatabletransposed};
\addplot [fill=green!70!blue] table [x=High, y expr=\coordindex] {\datatabletransposed};
\addplot [fill=red!70!white] table [x=Medium, y expr=\coordindex] {\datatabletransposed};
\addplot [fill=yellow] table [x=Low, y expr=\coordindex] {\datatabletransposed};
\legend{Yes, No}
\end{axis}
\end{tikzpicture}
