我想知道如何从 pgfplots 引脚选项中删除箭头。我不想要任何线条，只想要文本。
提前谢谢了！
编辑：添加的 MWE：
我想删除两个箭头，但只想保留文本。我还附上了输出。

答案1
我不明白pin如果您实际上喜欢（简单），为什么还要使用选项label。您还设置了一些图表默认的选项pgfplots。使用labels 的较短版本是：
\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\begin{document}
\begin{tikzpicture}[
every label/.style={label distance=5mm, font=\small}
]
\begin{axis}[
width = 8cm, height = 7cm,
xmin=0, xmax=0.2,
ymin=-0.01, ymax=1,
minor tick num={1}, %minor y tick num={1},
xlabel = Volume fraction ,
ylabel= {Area disorder (AD)},
legend pos= north east,
legend cell align=left,
y tick label style = {/pgf/number format/.cd, fixed,
fixed zerofill, precision=1},
x tick label style = {/pgf/number format/.cd, fixed,
fixed zerofill,precision=2},
mark size=1pt,
mark=square*,
]
\addplot [only marks, red, ] coordinates{(0.056,0.3759)
(0.097,0.4418)};
\coordinate[label=90:{9R}] (x) at (axis cs:0.097,0.4418);
\coordinate[label=90:{6R}] (x) at (axis cs:0.056,0.3759);
\end{axis}
\end{tikzpicture}
\end{document}

只需draw=none输入every pin edge/.style：
\documentclass{standalone}
\usepackage{amsmath, amssymb}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\usepackage{tikz}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\begin{document}
\begin{tikzpicture}[every mark/.append style={mark size=1pt}]
\begin{axis}[xmin=0, xmax=0.2, ymin=-0.01, ymax=1, width = 8cm, height = 7cm, xtick align =inside, ytick align =inside, ytick distance=0.2, xtick distance = 0.05, minor x tick num={1}, minor y tick num={1}, xlabel = Volume fraction , ylabel= {Area disorder (AD)}, legend style= {nodes={scale=0.5, transform shape}, legend pos= north east, legend cell align={left}}, y tick label style = {/pgf/number format/.cd,
use comma,
1000 sep={}, set decimal separator={.}, fixed,
fixed zerofill,
precision=1,
/tikz/.cd}, x tick label style = {/pgf/number format/.cd,
use comma,
1000 sep={}, set decimal separator={.}, fixed,
fixed zerofill,
precision=2,
/tikz/.cd}]
\addplot [only marks, red, mark=square*,mark options={solid, scale=0.6}] coordinates{(0.056,0.3759)};%\addlegendentry{6 wt\% CTBN};
\addplot [color= red, mark=square*,mark options={solid, scale=0.6}] coordinates{(0.097,0.4418)}; %\addlegendentry{9 wt\% CTBN};
\begin{scope}[
every pin edge/.style={draw=none}, % instead of ={<-,>=latex},
pin distance=1.5 cm,
every pin/.append style={font=\small}
]
\node[coordinate, pin={[fill=white, pin distance = 5 mm, inner sep=2pt]90:{9R}}]
at (axis cs:0.097,0.4418) {};
\node[coordinate, pin={[fill=white, pin distance = 5 mm, inner sep=2pt]90:{6R}}]
at (axis cs:0.056,0.3759) {};
\end{scope}
\end{axis}
\end{tikzpicture}

使用 PGFPlotsnodes near coords功能，您可以更简单地实现所需结果。有关详细信息，请查看代码中的注释。
% used PGFPlots v1.15
\documentclass[border=5pt]{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
xmin=0,
xmax=0.2,
ymin=-0.01,
ymax=1,
% -----
% (removed a lot of key--values irrelevant to the question)
% -----
% moved common options here
only marks,
mark options={
solid,
scale=0.6,
},
%%% added stuff to achieve what you want using PGFPlots `nodes near coords' feature
% just state that you want to use the feature
nodes near coords,
% by using the following key you can change the style of the nodes near coords
nodes near coords style={
font=\small,
yshift=3mm,
black,
},
]
% either you can use it using the `coordinates' syntax ...
\addplot [
red,
mark=square*,
% last you have to state the "type" of data you want to use
% for the `nodes near coords'. Here you you don't want to
% display numeric data, thus you have to use this value
point meta=explicit symbolic,
] coordinates {
(0.056,0.3759) [{6R}]
(0.097,0.4418) [{9R}]
};
% or which is even simpler to write using the `table' syntax
% (with the above explanations this here hopefully is pretty much
% self-explanatory)
\addplot [
blue,
mark=square*,
point meta=explicit symbolic,
] table [
x=x,
y=y,
meta=meta,
] {
x y meta
0.076 0.3759 6R
0.117 0.4418 9R
