pgfplots 图表标签（年/月）

我正在尝试使用@Jake 的答案来在 pgfplots 中的图表中添加多个标签（年份/月份）我添加了数据，但是图表看起来很奇怪：

在此处输入图片描述

我真的不知道如何解决这个问题。

这是我的图表的代码：

\begin{tikzpicture}

yticklabel style={append after command={(\tikzlastnode.east) edge +(0.15cm,0)}},

extra x tick style={
    yshift=-3.5ex,
    xticklabel=\year,
    xticklabel style={name={}},
    every x tick label/.style={}
},
xticklabel style={
    anchor=near xticklabel,
    alias=tick\ticknum,
    name=\ifnodedefined{start\year} % Have we already started this year?
        {end\year}  % Then this could be the last month
        {start\year}, % Otherwise, start the year
    append after command=
        \pgfextra{\pgfmathtruncatemacro\lastyear{\year-1}}
        \ifnodedefined{end\lastyear}
        {

            \fi}
        }
        {}
        \ifnum\ticknum>0
                \ifnum\month>1
                    \pgfextra{\pgfmathtruncatemacro\prevticknum{\ticknum-1}}

我将非常感激您的任何建议:)

更新

@khaled hariz 的答案不是我想要的，我需要我所展示的图表的外观。也许还有其他想法？

答案1

在@Jake 的回答中，每个月都有指定的数据，而这正是您遇到的情况所缺少的。

对于您的情况，您可以添加（幽灵）坐标来完成 2013-08-01 至 2015-09-01 期间的所有数据，缺失月份的数据可以作为没有标记的邻近坐标的平均值。

您的代码

你（们）能做到：

 \begin{tikzpicture}[>=stealth ]

    \begin{axis}[ width=9cm ,
    axis lines=middle ,
    xmin=0,xmax=10,
ymin=0,ymax=10,
ymajorgrids=true ,
ylabel near ticks ,
xlabel near ticks ,
xlabel= month,
ylabel=year,
%title=  ,
major grid style={ thick } ,
tick style={ thick } ,
axis line style={ thick } ,
ytick={ 0,...,10 } ,
xtick={ 0,...,10 } ,
ticklabel style={ font=\scriptsize } ,
enlargelimits={ abs=5mm}
]
\addplot[ ybar , fill =red , bar width=1mm] 
coordinates {(2,4)(3,5)(5,7)(7,10)
(8,2)(9,2)} ;

\end{axis}

\end{tikzpicture}
