    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!
