Apart from \kwrd{center}, some other \kwrd{loc} which can be specified are:

\begin{lstlisting}

'upper right'

'upper left'      

'lower left'      

'lower right'     

'center left'     

'center right'    

'lower center'    

'upper center'

One can also mention explicit co-ordinates for placement of legend. 

\subsection{Colors of plots}

\typ{In []: plot(y, sin(y), 'g')}\\

Plots graph with green color. Other options available are:

\begin{lstlisting}

  'r' ---> Red

  'b' ---> Blue

  'r' ---> Red 

  'c' ---> Cyan 

  'm' ---> Magenta

  'y' ---> Yellow

  'k' ---> Black 

  'w' ---> White

\end{lstlisting}

  \item \typ{\%hist}\\

  It returns the logs of all commands(including mistakes) used in IPython interpreter.

  \item \typ{\%hist -n}\\

It disables the line number representation of logs.

  \item \typ{\%save four\_plot.py 16 18-27}\\

For creating a script named four\_plot which includes line 16 and line 18 to 27 of logs.

  \item \typ{\%run -i four\_plot.py}\\

Running the python script inside IPython interpreter.

\section{Example}

  \begin{lstlisting}

In []: x = linspace(0, 2*pi, 50)

In []: plot(x, sin(x), 'g')

In []: plot(x, cos(x), 'r', linewidth=2)

In []: xlabel('x')

In []: title('Sinusoidal Waves')

In []: legend(['sin(x)', 'cos(x)'])

In []: annotate('origin', xy=(0, 0))

In []: xmin, xman = xlim()           # Without arguments gets

In []: ymin, ymax = ylim()           # values

In []: xlim(0, 2 * pi)               # With values, sets the

In []: ylim(ymin - 0.2, ymax + 0.2)  # specified values

In []: savefig('sin.png')   # Save figure

In []: close()              # Closes the figure
