如何从上到下标记 pgfplot？

Question

我刚开始在论文中使用 pgfplots 绘制图表。我使用的是双列布局，并希望创建图表时尽可能将它们放在单列中。

我觉得读者需要将头向左倾斜才能阅读 y 轴标签，这有点烦人。我想知道我是否可以将 y 轴标签设置为如下所示：

这是用于测试目的的小图表：

\begin{tikzpicture} 
\begin{axis}[   
    ybar,
    ymajorgrids,
    axis lines*       = left,
    ylabel            = {Lorem},       
    xlabel            = {Ipsum},
    xtick             = {2016, 2017, 2018, 2019},
    symbolic x coords = {2016, 2017, 2018, 2019},
]
    \addplot[red!20!black,fill=red!80!white] coordinates
    {(2016,58.8) (2017,93.7) (2018,96.5) (2019,96.4)};
    
    \addplot[red!20!black,fill=blue!80!white]coordinates
    {(2016,93.8) (2017,87.3) (2018,82.3) (2019,77.7)};

\end{axis}
\end{tikzpicture}

Answer 1

@abcdefg 提供的解决方案：

ylabel 样式 = {旋转 = -90, 对齐 = 居中},
ylabel = {L\o\r\e\m},

例子：

\begin{tikzpicture} 
\begin{axis}[   
    ybar,
    ymajorgrids,
    axis lines*       = left,
    ylabel style      = {rotate = -90, align = center},     
    ylabel            = {L\\o\\r\\e\\m},     
    xlabel            = {Ipsum},
    xtick             = {2016, 2017, 2018, 2019},
    symbolic x coords = {2016, 2017, 2018, 2019},
]
    \addplot[red!20!black,fill=red!80!white] coordinates
    {(2016,58.8) (2017,93.7) (2018,96.5) (2019,96.4)};
    
    \addplot[red!20!black,fill=blue!80!white]coordinates
    {(2016,93.8) (2017,87.3) (2018,82.3) (2019,77.7)};

\end{axis}
\end{tikzpicture}
