我的大部分符号 x 坐标都没有显示出来

Question

这一点我还没弄清楚。

这是一个非常基本的条形图，我symbolic x coords试图显示年份。但是只显示了第一年，而且与它应该表示的列相差甚远。我试过使用xtick=data,和xtick={2001,2002,...,2016},，也试过xticklabel而不是xtick。

我知道我需要减小此图表中符号 x 的字体大小。但我觉得很奇怪，我只得到一年。我甚至对周期标签也感到满意。

它看起来是这样的

这是一个 tikz 程序，它显示了我认为你想要的图片。我没有足够的知识来指出你的程序中的错误，而是在 pgfplots 手册中找到了一个合理的例子： https://pgfplots.sourceforge.net/example_78.tex

\documentclass[tikz]{standalone}
\usepackage[icelandic]{babel}

\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
 \begin{axis}[

    xmin=2000.20,xmax=2016.4,
    xtick={2001,2002,...,2016},
    x tick label style={font=\footnotesize,rotate=45,anchor=east},
    ybar=2pt,
    bar width=4pt,
    ymajorgrids=true,
    grid style=dashed,
    xlabel={Ár},

    \addplot[red,fill] coordinates { (2001,6.5)(2002,7.3)
