看起来 xticks 没有完全对齐条形,缺少第一个 AAA:
\documentclass[]{standalone}
\usepackage{pgfplotstable}
\usepackage{tikz}
\tikzset{font=\footnotesize}
\pgfplotstableread[col sep=comma]{
key,value
AAA,14.9
BBB,16.5
CCC,19.1
DDD,20.2
EEE,22.7

HHH,26.4
III,27.1
JJJ,30.8
KKK,35.5

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

输出:
答案1
首先,您的图缺少关键
xtick=data
。然后 xtick 标签和数据匹配。您可能不希望第一个条形图仅打印一半在 y 轴旁边。请
xmin = 0,xmax=14
用替换xmin = -1,xmax=13
。也许你不希望 y 轴从最小值(即 )开始
AAA
。在这种情况下,请添加ymin=0
。要将 x 轴的标签向下移动,请使用
xlabel style = {yshift=-5mm}
。
