# How to remove arrow from the Pgfplot pin option?

I was wondering how to remove arrow from pgfplots pin option. I do not want any line and want only text.

I would like to remove the two arrows but want to keep the text only. I am also attaching the output.

\documentclass{standalone}
\usepackage{amsmath, amssymb}
\usepackage{pgfplots}
\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,

/tikz/.cd}]

\begin{scope}[
every pin edge/.style={<-,>=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}

\end{document}
• Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Stefan Pinnow Mar 6 '18 at 21:27

i don't understand why you use pin option if you actually like to have (simple) label. also you set some options which are default for pgfplots diagrams. shorter version with use of labels is:

\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 ,
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}

which gives:

Just put draw=none for 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}]

\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}

\end{document}

You can achieve the desired result in a much simpler way when you use the PGFPlots nodes near coords feature. For details please have a look at the comments in the code.

% 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 ...
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)
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
};
\end{axis}
\end{tikzpicture}
\end{document}
