我们怎样才能用条形图固定 x 轴上的图例？

Question

我们如何解决 x 轴的问题？另外，是否可以在每列的上方或中间写上每个数字？

为了制作条形图，我使用了以下代码：

\documentclass{article}

\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
\begin{axis}[
        width  = 0.85*\textwidth,
        height = 8cm,
        major x tick style = transparent,
        ybar=2*\pgflinewidth,
        bar width=14pt,
        ymajorgrids = true,
        ylabel = {Deaths per 1,000 live births},
        symbolic x coords={World,Low income,Middle income, High income},
        xtick = data,
        scaled y ticks = false,
        enlarge x limits=0.25,
        ymin=0,
        legend cell align=left,
        legend style={
                at={(1,1.05)},
                anchor=south east,
                column sep=1ex
        }
    ]
\addplot
coordinates
{(World,51) (Low income,95) (Middle income,46) (High income,6)};
\addplot
coordinates
{(World,63) (Low income,115) (Middle income,57) (High income,7)};
\addplot
coordinates
{(World,73) (Low income,133) (Middle income,67) (High income,7)};
\addplot
coordinates
{(World,87) (Low income,164) (Middle income,82) (High income,12)};
\legend
{2011,2005,2000, 1990}
\end{axis}
\end{tikzpicture}
\end{document}

Answer 1

我使用选项{axis}[nodes near coords, x tick label style={rotate=45,anchor=east},]，也许你可以尝试一下。

1. nodes near coords为每个条形添加值。
2. x tick label style={rotate=45,anchor=east},以 45 度角旋转标签。

对于栏太宽，我认为bar width=12pt已经足够了。
