\frametitle{Scatter plot}
\label{sec-4}

  Scatter plot - a collection of points,where each point determines
  it's position on the horizontal axis and the vertical axis 
  respectively.

\end{frame}
\begin{frame}[fragile]
\frametitle{Exercise 3: Pie chart}
\label{sec-9}

  Plot a pie chart representing the profit percentage of company A, with the data 
  from the file \verb~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{\verb~pie()~ function}
\label{sec-10}


\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-11}

  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-12}

  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-13}

  Plot a bar chart representing the profit percentage of company A, with the data 
  from the file \verb~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{\verb~bar()~ function}
\label{sec-14}


\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}
\end{itemize}
\begin{verbatim}
   In []: bar(year, profit)
\end{verbatim}
\end{frame}
\begin{frame}
\frametitle{Exercise 6: Bar chart}
\label{sec-15}

  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 \verb~company-a-data.txt~.

\frametitle{Summary}
\label{sec-20}

  In this tutorial we learnt to,
 

\begin{itemize}
\item Plot a scatter plot using ``scatter()`` function
\item Plot a pie chart using ``pie()`` function
\item Plot a bar chart using ``bar()`` function
\item Plot a log-log graph using ``loglog()`` function
\item Access the \verb~matplotlib~ online help.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Evaluation}
\label{sec-21}


\begin{enumerate}
\item ``scatter(x, y, color='blue', marker='d')`` and ``plot(x, y,
     color='b', marker='d')`` does exactly the same.
\begin{itemize}
\item True
\item False
\end{itemize}
\item What statement can be issued to generate a bar chart with vertical
     line hatching.
\begin{itemize}
\item bar(x, y, color='w', hatch='/')
\item bar(x, y, fill=False, hatch='//')
\item bar(x, y, fill=False, hatch='|')
\item bar(x, y, color='w', hatch='\')
\end{itemize}
\end{enumerate}
\end{frame}
\begin{frame}
\frametitle{Solutions}
\label{sec-22}


\begin{enumerate}
\item False
\item bar(x, y, fill=False, hatch='|')
