# Center the axes in the coordinate origin

I need to center the axes in the coordinate origin. The axes not center, can see axis y extend (circle red).

Ty for help me :D


...

\pgfplotsset{compat=1.11}

...

\begin{document}

\begin{tikzpicture}[scale=1.5]
\begin{axis} [
xlabel = \textit{Voltage},
ylabel = \textit{Current},
axis lines = middle,
enlarge y limits = true,
xmin = 0, xmax = 90,
ymin = 0, ymax = 150,
width=15cm, height=8cm,
grid = major,
grid style = {dashed, line width=.1pt, draw=gray!30},
legend pos = north east,
]

\addplot table[x index = {0}, y index = {1}]{\mydata};
\legend{Townsend}

\end{axis}
\end{tikzpicture}

\end{document}


Your problem is simply the option enlarge y limits, which you should set to false instead of true.
