\frametitle{Exercise 1: Scatter plot}
\label{sec-2}

  to 2010. The data for the same is available in the file \texttt{company-a-data.txt}.
\end{frame}
\begin{frame}[fragile]
\frametitle{\texttt{scatter()} function}
\label{sec-3}

\begin{itemize}
\item \emph{Syntax :} scatter(x,y)

\begin{itemize}
\item x, a sequence of data
\item y, a sequence of data, the same length of x
\end{itemize}

\end{itemize}

\begin{verbatim}
   In []: scatter(year, profit)
\end{verbatim}

\begin{frame}[fragile]
\frametitle{Exercise 2: Scatter plot}
\label{sec-4}

  Plot a scatter plot of the same data in \texttt{company-a-data.txt} with red diamond markers.
\begin{verbatim}
   
\end{verbatim}

  \textbf{Clue} - \emph{try scatter? in your ipython interpreter}
\end{frame}
\begin{frame}
\frametitle{Pie chart}
\label{sec-5}

  Pie chart - a circle graph divided into sectors, illustrating proportion. 
\end{frame}
\begin{frame}[fragile]
\frametitle{Exercise 3: Pie chart}
\label{sec-6}

  Plot a pie chart representing the profit percentage of company A, with the data 
  from the file \texttt{company-a-data.txt}.
\begin{verbatim}
   
\end{verbatim}

  \emph{(we can reuse the data in lists year and profit)}
\end{frame}
\begin{frame}[fragile]
\frametitle{\texttt{pie()} function}
\label{sec-7}

\begin{itemize}
\item \emph{Syntax :} pie(values, labels=labels)

\begin{itemize}
\item values, the data to be plotted
\item labels, the label for each wedge in the pie chart
\end{itemize}

\end{itemize}

\begin{verbatim}
   In []: pie(profit, labels=year)
\end{verbatim}
\end{frame}
\begin{frame}[fragile]
\frametitle{Exercise 4: Pie chart}
\label{sec-8}

  Plot a pie chart with the same data with colors for each wedges as white, red, 
  magenta, yellow, blue, green, cyan, yellow, magenta, and blue.
\begin{verbatim}
   
\end{verbatim}

  \textbf{Clue} - \emph{try pie? in your ipython interpreter}
\end{frame}
\begin{frame}
\frametitle{Bar chart}
\label{sec-9}

  Bar chart - a chart with rectangular bars with lengths proportional 
  to the values that they represent.
\end{frame}
\begin{frame}[fragile]
\frametitle{Exercise 5: Bar chart}
\label{sec-10}

  Plot a bar chart representing the profit percentage of company A, with the data 
  from the file \texttt{company-a-data.txt}.

\label{sec-11}

\begin{itemize}
\item \emph{Syntax :} bar(x, y)

\begin{itemize}
\item x, a sequence of data
\item y, a sequence of data, the same length of x
\end{itemize}

\begin{verbatim}
   In []: bar(year, profit)
\end{verbatim}
\end{frame}
\begin{frame}
\frametitle{Exercise 6: Bar chart}
\label{sec-12}

  Plot a bar chart which is not filled and which is hatched with 
    $45^o$
  slanting lines as shown in the image. The data for the chart may be
  obtained from the file \texttt{company-a-data.txt}.

\begin{itemize}
\item Log-log graph

\begin{itemize}
\item 2-dimensional graph.
\item uses logarithmic scales on both axes.
\item graph appears as straight line due to non-linear scaling.
