水平对齐组图标题

我想知道为什么我的地块标题不是水平对齐的。我尝试了几个来源，但找不到控制标题对齐的选项。下图是我得到的。正如你所见，金斯伯里和诺斯科特不在同一水平面上。

标题不一致的集体阴谋

这是我的乳胶代码

答案1

正如我在评论中提到的，将您的groupplot设置更改为：

\begin{groupplot}[%
    group style={%
        group name=QuantileError,%
        group size= 2 by 1,%
        horizontal sep = 0.1cm,
    },%
    width=0.3\textwidth,
    height=0.4\textwidth,
    legend cell align={left}, %
    legend style={draw=white, fill=mygrey3},%
    every axis label/.style={font=\small},%
    ticklabel style = {font=\tiny},%
    yticklabel style={/pgf/number
        format/.cd,fixed,precision=4,zerofill,/tikz/.cd},%
    x tick label style={rotate=90, anchor=east},
    scaled x ticks=false,
    xticklabel style={/pgf/number
        format/.cd,fixed,precision=2,zerofill,/tikz/.cd},
    title style = {text depth=0.5ex}                       % <--- added
   ]%

您将获得期望的结果：

您可以将选项添加 title style={text depth = 0pt}到\nextgroupplot[...]两个图中，并将所有内容水平对齐。

答案3

前两个答案的替代方法是将标题文本锚定到顶部（北），并在标题和图表之间增加一些距离title style={anchor=north, yshift=2ex}。

Zarko 的评论解释了问题的原因。这就是为什么带有“g”和“y”的标题比另一个标题高的原因。我的解决方案是将标题文本与字母顶部对齐，而不是底部。但这会导致情节与标题重叠。所以我们必须用 yshift 在它们之间增加一些距离。

\begin{groupplot}[%
    group style={%
        group name=QuantileError,%
        group size= 2 by 1,%
        horizontal sep = 0.1cm,
    },%
    width=0.3\textwidth,
    height=0.4\textwidth,
    legend cell align={left}, %
    legend style={draw=white, fill=mygrey3},%
    every axis label/.style={font=\small},%
    ticklabel style = {font=\tiny},%
    yticklabel style={/pgf/number
        format/.cd,fixed,precision=4,zerofill,/tikz/.cd},%
    x tick label style={rotate=90, anchor=east},
    scaled x ticks=false,
    xticklabel style={/pgf/number
        format/.cd,fixed,precision=2,zerofill,/tikz/.cd},
    title style={anchor=north, yshift=2ex}               % <--- FIX
   ]%
