Overview
Often times a document needs to include a chart, graphs or other images. There are essentially two ways this can be accomplished.
The first is to include a image file in the document, the second is to use the pgf-plots package to generate a chart.
Including a Chart Image
One way to inlcude a chart is to generate the chart first as an image file, such as a png or jpg. Then to include the image in the latex as follows.
\begin{figure}
\includegraphics[width=\linewidth]{chart.jpg}
\caption{A Chart}
\label{fig:chart}
\end{figure}
Pgf-Plots
The Pgf-Plots library is used to generate a chart that is rendered within the document. Pgf Plots uses the tikz package, which should be included at the top of the document.
(see tikz)
\usepackage{tikz}
The following is a sample pgf-plot.
\begin{tikzpicture}
\begin{axis}[
width=1.0\textwidth,
height=1.0\textwidth,
title=pgf plotline,
xlabel={},
ylabel={},
]
\addplot[color2] coordinates{

};
\end{axis}
\end{tikzpicture}
