+
+* Outline
+  - Saving plots.
+  - Plotting in different formats.
+  - Locating the file in the file system.
+
+* Creating a basic plot
+  Plot a sine wave from -3pi to 3pi.
+  #+begin_src python
+    In []: x = linspace(-3*pi,3*pi,100)
+    
+    In []: plot(x, sin(x))
+  #+end_src
+* savefig()
+** savefig() - to save plots
+   : syntax: savefig(fname)
+** example
+*** savefig('/home/fossee/sine.png')    
+   - file sine.png saved to the folder /home/fossee
+   - .png - file type
+
+* More on savefig()
+** Recall
+   - .png - file type
+** File types supported
+*** .pdf - PDF(Portable Document Format)
+*** .ps - PS(Post Script)
+*** .eps - Encapsulated Post Script
+    ~to be used with~ LaTeX ~documents~
+*** .svg - Scalable Vector Graphics
+    ~vector graphics~
+*** .png - Portable Network Graphics
+    ~supports transparency~
+* Exercise 1
+  Save the sine plot in the format EPS which can be embedded in LaTeX documents.
+* Solution 1
+  #+begin_src python
+    savefig('/home/fossee/sine.eps')
+  #+end_src
+* Exercise 2
+  Save the sine plot in PDF, PS and SVG formats.
+
+* Summary
+  You should now be able to
+  - Use ~savefig()~ function
+  - Save plots in different formats
+      - PDF
+      - PS
+      - PNG
+      -	SVG
+      - EPS
+  - Locating the files in file system.
+    
+* Thank you!
