如何在龙卷风图中更改 x-achsis 的基准值？

我正在尝试绘制一个龙卷风图，其中 x 轴上的基值不同于零，在我的情况下是 5.43。

\documentclass[margin=5pt]{standalone}

\usepackage{tikz,pgfplots,pgfplotstable}

\pgfplotstableread[col sep=comma, header=true]{
parameter,      50,     200
Material cost,  3.67,   8.69
E\&U cost,      5.13,   5.78
FCOP,           4.86,   6.31
ACC,            5.04,   5.94
}\loadedtable

\begin{document}
    \begin{tikzpicture}
        \begin{axis}[
            enlarge x limits=0.2,
            %xmin=0,
            xmax=10,
            %xticklabels={0,2,4,6,8,10},
            xbar,nodes near coords,bar width=16pt,bar shift=0pt,
            symbolic y coords={Material cost, E\&U cost, FCOP, ACC },
            ytick={Material cost, E\&U cost, FCOP, ACC },
            y dir = reverse,
            ]
            \addplot[nodes near coords align={left},
            draw=blue,fill=blue!25,text=blue]
            table[y=parameter,x expr={-\thisrow{50}},point meta={-x}] \loadedtable;
            \addplot table[y=parameter,x expr={\thisrow{200}}] \loadedtable;
        \end{axis}
    \end{tikzpicture}
\end{document}

变体这个很好的解决方案就是要改变标签X 轴为 5.43。请注意，您不需要加载tikz，pgfplots如果您加载它们，则无论如何都会加载，但是如果您使用，则pgfplotstable应该添加：\pgfplotsset{compat=1.18}pgfplots

\documentclass[border=10pt]{standalone}
\usepackage{pgfplotstable}
\pgfplotsset{compat=1.18}

\pgfplotstableread[col sep=comma, header=true]{
parameter,      50,     200
Material cost,  3.67,   8.69
E\&U cost,      5.13,   5.78
FCOP,           4.86,   6.31
ACC,            5.04,   5.94
}\loadedtable

\begin{document}
    \begin{tikzpicture}
        \begin{axis}[
            enlarge x limits=0.2,
            %xmin=0,
            xmax=10,
            %xticklabels={0,2,4,6,8,10},
            xbar,
            nodes near coords,
            bar width=16pt,
            bar shift=0pt,
            symbolic y coords={Material cost, E\&U cost, FCOP, ACC},
            ytick={Material cost, E\&U cost, FCOP, ACC},
            y dir=reverse,
            xticklabel={\pgfmathparse{\tick+5.43}\pgfmathprintnumber{\pgfmathresult}}]
        ]
            \addplot[nodes near coords align={left},
                draw=blue, fill=blue!25, text=blue]
                table[y=parameter, x expr={-\thisrow{50}}, point meta={-x}] \loadedtable;
            \addplot table[y=parameter, x expr={\thisrow{200}}] \loadedtable;
        \end{axis}
    \end{tikzpicture}
\end{document}

也许这就是你想要的：

\documentclass[border=10pt]{standalone}
\usepackage{pgfplotstable}
\pgfplotsset{compat=1.18}

\pgfplotstableread[col sep=comma, header=true]{
parameter,      50,     200
Material cost,  3.67,   8.69
E\&U cost,      5.13,   5.78
FCOP,           4.86,   6.31
ACC,            5.04,   5.94
}\loadedtable

\begin{document}
    \begin{tikzpicture}
        \begin{axis}[
            enlarge x limits=0.2,
            %xmin=0,
            %xmax=2,
            %xticklabels={0,2,4,6,8,10},
            xbar,
            nodes near coords,
            bar width=16pt,
            bar shift=0pt,
            symbolic y coords={Material cost, E\&U cost, FCOP, ACC},
            ytick={Material cost, E\&U cost, FCOP, ACC},
            y dir=reverse,
            xticklabel={\pgfmathparse{\tick+5.43}\pgfmathprintnumber{\pgfmathresult}}]
        ]
            \addplot[nodes near coords align={left},
                draw=blue, fill=blue!25, text=blue]
                table[y=parameter, x expr={\thisrow{50}-5.43}, point meta={-x}] \loadedtable;
            \addplot table[nodes near coords align={right},
                y=parameter, x expr={\thisrow{200}-5.43}, point meta={x}] \loadedtable;
        \end{axis}
    \end{tikzpicture}
\end{document}

谢谢 - 后者是我想要的。在这种情况下，我可以将值显示为 %，并且不需要 x 轴偏移。

        y dir = reverse,
        legend pos=south east,
        legend style={

        \addplot[nodes near coords align={left},
