# Draw angle between axis and line using pgfplots

i tried to draw a angle between a line, and the X axis using pgfplots, i saw a lot of ways using tikz and other packages but, there is any way to do this using pgfplots?

\documentclass{article}

\usepackage{pgfplots}

\begin{document}

\begin{tikzfigure}
\begin{axis}[
axis x line = center,
axis y line = center,
xlabel = $x$,
ylabel = $y$,
xmin=-1.0,
xmax=3.0,
ymin=-1.0,
ymax=3.0,
disabledatascaling,
axis equal,
]
\addplot [->, color=blue] coordinates {(0, 0) (2, 3)};
\end{axis}

\end{tikzfigure}
\end{document}


What can i write to get an angle like this?

Not directly, but I also do not see a need for that. But of course you can just define 3 coordinates and then use the angles library to draw angles were needed.

% used PGFPlots v1.17
\documentclass[border=5pt]{standalone}
\usepackage{pgfplots}
\usetikzlibrary{
angles,
quotes,
}
% use this compat level or higher so TikZ coordinates
% are in axis units by default
\pgfplotsset{compat=1.11}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
axis lines=center,
xlabel=$x$,
ylabel=$y$,
xmin=-1.0,
xmax=3.0,
ymin=-1.0,
ymax=3.0,
disabledatascaling,
axis equal,
]
\coordinate (xaxis) at (\pgfkeysvalueof{/pgfplots/xmax},0);
\coordinate (origin) at (0,0);
\addplot [->,blue] coordinates {(0, 0) (2, 3)}
coordinate [at end] (A)
;
\path (xaxis) -- (origin) -- (A)
