将 x 刻度标签位置设置为轴的底部

将 x 刻度标签位置设置为轴的底部

我终于设法用 将数据置于中心axis x line*=center，但我还没有找到将数据置于图底部的方法x tick labels。我已经绘制了一些主要网格线，现在我想将刻度标签置于图底部。

我曾尝试使用at={()}，但似乎不起作用。

刻度标签现在位于轴上。

\documentclass{standalone}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
    \pgfplotstableread{data/multicontrol.dat}\datatable

    \begin{axis}[ybar=0,
    bar width={0.2cm},
    xticklabels from table={\datatable}{variable},
    xtick=data,
    x tick label style={
        rotate=60,anchor=east},
    yticklabels={X,Very Bad, Bad, Neutral, Good, Very Good},
    xmajorgrids,
    ymin=-2,
    ymax=2,
    axis x line*=middle,
    axis y line*=left,
    enlarge x limits,
    y filter/.code={\pgfmathparse{#1-3}}
    ]

    \addplot table[x=X,y=old] {\datatable};
    \addlegendentry{Joystick}
    \addplot table[x=X,y=new] {\datatable};
    \addlegendentry{Mouse}
    \end{axis}
\end{tikzpicture}
\end{document}

示例数据：

X   variable                    old         new
1   {Know where I am}           2.375       4
2   {Know what I see}           3.375       4.375
3   {See target directly}       2.428571429 4.5
4   {Know origin}               3.875       4.285714286
5   {Direct Adjustment (inv)}   2.625       3.75
6   {Screen position}           3.25        4.125
7   {Expectation}               2.25        2.375
8   {Get lost (inv)}            2.714285714 3.5
9   {Number dependent (inv)}    2           4

答案1

这里最简单的做法是使用axis x line*=left（而不是中间），将轴线和标签放置在图的底部，并使用以下方法之一“伪造”零线如何在绘图中添加零线？。

对于此图，我建议翻转轴吗？这样可以更轻松地读取标签，因为您无需旋转即可完成：

\usepackage{pgfplots}

\begin{document}
