我想创建一个明确的结构。这是一个百分比图表。
这是我的目标，我想要得到这个：
我尝试使用此代码
\documentclass[a4paper,twoside,12pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8x]{inputenc}
\usepackage[english]{babel}
\usepackage{pgfplotstable}
\definecolor{color1}{rgb}{0.98, 0.81, 0.69}
\definecolor{color2}{rgb}{0.55, 0.71, 0.0}
\definecolor{color3}{rgb}{1.0, 0.6, 0.4}
\definecolor{color4}{rgb}{0.29, 0.59, 0.82}
\pgfplotscreateplotcyclelist{mycolor}{
{fill=color1!80, draw=color1},
{fill=color2!80, draw=color2},
{fill=color3!80, draw=color3},
{fill=color4!80, draw=color4},
}
\pgfplotsset{
discard if/.style 2 args={
x filter/.code={
\ifdim\thisrow{#1} pt=#2pt
\def\pgfmathresult{inf}
\fi
}
},
discard if not/.style 2 args={
x filter/.code={
\ifdim\thisrow{#1} pt=#2pt
\else
\def\pgfmathresult{inf}
\fi
}
}
}
\begin{filecontents*}{coefficienti.dat}
T K Q Kf n
400 0.0463 32.9 5.78 0.321
500 0.124 24.8 6.30 0.275
600 0.115 24.6 6.30 0.261
700 1.64 24.4 11.9 0.151
\end{filecontents*}
\begin{document}
\begin{tikzpicture}
\begin{axis} [
ymin=0,
ybar=0, bar width=20, bar shift=0,
xtick={data},
ymajorgrids=true,
cycle list name=mycolor,
nodes near coords,
every node near coord/.append style = {
/pgf/number format/.cd,
fixed,
fixed zerofill,
precision=3
}]
% first complete plot to place the x-axis labels
\addplot+ table[x=T,y=K] {coefficienti.dat};
% the bars with different colors
\pgfplotsinvokeforeach{500,600,700}{
\addplot+[discard if not={T}{#1}] table[x=T,y=K] {coefficienti.dat};
}
\end{axis}
\end{tikzpicture}
\end{document}
但在那个基础上我无法写文字。
有人可以帮我创建百分比图表。
任何想法？
非常感谢

最简单的方法是将标签添加到数据文件本身。然后你“仅”需要“稍微”更改代码，即可获得所需的结果。
% used PGFPlots v1.16
% added `xlables' column
\begin{filecontents*}{coefficienti.dat}
T K Q Kf n xlables
400 0.0463 32.9 5.78 0.321 {VISA}
500 0.124 24.8 6.30 0.275 {MasterCard}
600 0.115 24.6 6.30 0.261 {American \\ Express}
700 1.64 24.4 11.9 0.151 {Union Pay \\ (China)}
\end{filecontents*}
\documentclass[border=5pt]{standalone}
\usepackage{pgfplotstable}

\definecolor{color2}{rgb}{0.55, 0.71, 0.0}
\definecolor{color3}{rgb}{1.0, 0.6, 0.4}
\definecolor{color4}{rgb}{0.29, 0.59, 0.82}

您可以使用以下方式指定轴标签上的文本xticklabels={Visa,Mastercard, American Express, Union Pay, JCB}
\documentclass[a4paper,twoside,12pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8x]{inputenc}

\definecolor{color2}{rgb}{0.55, 0.71, 0.0}
\definecolor{color3}{rgb}{1.0, 0.6, 0.4}
\definecolor{color4}{rgb}{0.29, 0.59, 0.82}
\pgfplotscreateplotcyclelist{mycolor}{
{fill=color1!80, draw=color1},
{fill=color2!80, draw=color2},
{fill=color3!80, draw=color3},
{fill=color4!80, draw=color4},
}
\pgfplotsset{
discard if/.style 2 args={
x filter/.code={
\ifdim\thisrow{#1} pt=#2pt
\def\pgfmathresult{inf}
\fi
}
},
discard if not/.style 2 args={
x filter/.code={
\ifdim\thisrow{#1} pt=#2pt
\else
\def\pgfmathresult{inf}
\fi
}
}
}
