I am trying to put three graphs side by side in two column format. The figures is shown below.
My LaTeX code is as following:
\begin{figure*}
\centering

\label{fig:graph1}
\begin{tikzpicture}[yscale=0.7, xscale=0.7]
\begin{axis}[

ymin= 0,ymax=1,
xlabel=\emph{User Requests},ylabel=\emph{$E_{res}$ Percent},
xtick={0,10,20,...,100},
ytick={0,0.1,0.2,...,1},
legend style={legend pos=north east}
]
\addplot coordinates{(0,1.0) (10,0.96) (20,0.90) (30,0.85) (40,0.81)

\end{axis}

My problem: The graphs are not set in a single row.
