Here's an option using pgfplots, which can be compiled with pdflatex



\documentclass{article}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}[&gt;=stealth]
    \begin{axis}[
        xmin=-4,xmax=4,
        ymin=-2,ymax=2,
        axis x line=middle,
        axis y line=middle,
        axis line style=&lt;-&gt;,
        xlabel={$x$},
        ylabel={$y$},
        ]
        \addplot[no marks,blue,&lt;-&gt;] expression[domain=-pi:pi,samples=100]{sin(deg(2*x))+1/2} 
                    node[pos=0.65,anchor=south west]{$y=\sin(2x)+\frac{1}{2}$}; 
    \end{axis}
\end{tikzpicture}
\end{document}


One of the main reasons I like this package, is that global styles can be specified easily in the preamble. So, if you're going to have more than one of these plots, it might be a good idea to use something like the following setup

\documentclass{article}
\usepackage{pgfplots}

% axis style
\pgfplotsset{every axis/.append style={
                    axis x line=middle,    % put the x axis in the middle
                    axis y line=middle,    % put the y axis in the middle
                    axis line style={&lt;-&gt;}, % arrows on the axis
                    xlabel={$x$},          % default put x on x-axis
                    ylabel={$y$},          % default put y on y-axis
                    }}

% line style
\pgfplotsset{mystyle/.style={color=blue,no marks,line width=1pt,&lt;-&gt;}} 

% arrow style: stealth stands for 'stealth fighter' 
\tikzset{&gt;=stealth}

\begin{document}
\begin{tikzpicture}
    \begin{axis}[
        xmin=-4,xmax=4,
        ymin=-2,ymax=2,
        ]
        \addplot[mystyle] expression[domain=-pi:pi,samples=100]{sin(deg(2*x))+1/2} 
                    node[pos=0.65,anchor=south west]{$y=\sin(2x)+\frac{1}{2}$}; 
    \end{axis}
\end{tikzpicture}
\end{document}


How can I make a graph of a function?
I am trying to find conference rank of International Conference on Information and Communication Systems (ICICS) but was not successful. On core, International Conference on Information and Communication Security is listed.Could not locate it on Google scholar. Does it mean this conference is not ranked and publication from this conference will not hold any importance !?
