    32 * Outline
       
    33   - Saving plots.
       
    34   - Plotting in different formats.
       
    35   - Locating the file in the file system.
       
    36 
       
    37 * Creating a basic plot
       
    38   Plot a sine wave from -3pi to 3pi.
       
    39   #+begin_src python
       
    40     In []: x = linspace(-3*pi,3*pi,100)
       
    41     
       
    42     In []: plot(x, sin(x))
       
    43   #+end_src
       
    44 * savefig()
       
    45 ** savefig() - to save plots
       
    46    : syntax: savefig(fname)
       
    47 ** example
       
    48 *** savefig('/home/fossee/sine.png')    
       
    49    - file sine.png saved to the folder /home/fossee
       
    50    - .png - file type
       
    51 
       
    52 * More on savefig()
       
    53 ** Recall
       
    54    - .png - file type
       
    55 ** File types supported
       
    56 *** .pdf - PDF(Portable Document Format)
       
    57 *** .ps - PS(Post Script)
       
    58 *** .eps - Encapsulated Post Script
       
    59     ~to be used with~ LaTeX ~documents~
       
    60 *** .svg - Scalable Vector Graphics
       
    61     ~vector graphics~
       
    62 *** .png - Portable Network Graphics
       
    63     ~supports transparency~
       
    64 * Exercise 1
       
    65   Save the sine plot in the format EPS which can be embedded in LaTeX documents.
       
    66 * Solution 1
       
    67   #+begin_src python
       
    68     savefig('/home/fossee/sine.eps')
       
    69   #+end_src
       
    70 * Exercise 2
       
    71   Save the sine plot in PDF, PS and SVG formats.
       
    72 
       
    73 * Summary
       
    74   You should now be able to
       
    75   - Use ~savefig()~ function
       
    76   - Save plots in different formats
       
    77       - PDF
       
    78       - PS
       
    79       - PNG
       
    80       -	SVG
       
    81       - EPS
       
    82   - Locating the files in file system.
       
    83     
       
    84 * Thank you!
