-Objective Questions
--------------------
-
-.. A mininum of 8 questions here (along with answers)
-
-
-1. What argument can be used with savefig to increase the resolution
- of the plot while saving a plot.
-
- a. fname
- #. transparency
- #. dpi
- #. format
-
-Answer: dpi
-
-2. The fname argument of savefig has to be always absolute path.
-
- a. True
- #. False
-
-Answer: False
-
-3. You are right now in the directory `/home/fossee`, from the
- following which one is the correct one in-order to save the plot as
- svg with the filename `plot` to the directory `/home/fossee/sine/`
-
- a. savefig('/sine/plot.svg')
- #. savefig('sine/plot.svg')
- #. savefig('home/fossee/sine/plot.svg')
- #. All of these
- #. None of the above
-
-Answer: savefig('sine/plot.svg')
-
-4. Which is the best image format to be used with Latex documents
- which savefig supports?
-
- a. SVG - Scalable Vector Graphics
- #. EPS - Encapsulated Post Script
- #. PS - Post Script
- #. PNG - Portable Network Graphics
- #. None of the above
-
-Answer: EPS - Encapsulated Post Script
-
-5. ``savefig('sine.png')`` saves the plot in,
-
- a. The root directory ``/`` (on GNU/Linux, Unix based systems)
- ``c:\`` (on windows).
- #. Will result in an error as full path is not supplied.
- #. The current working directory.
- #. Predefined directory like ``/documents``.
-
-Answer: The current working directory.
-
-6. Study the following code and tell what will happen,
- ::
- savefig('cosine.png',facecolor='blue')
-
- a. Will generate an error as plot statements are missing
- #. Will generate an error as full path is not specified
- #. Create a file ``cosine.png`` with blue background at the current
- working directory.
- #. Create a file ``cosine.png`` with blue background at a
- predefined directory like ``/documents``.
-
-Answer: Create a file ``cosine.png`` with blue background at the
- current working directory.
-
-7. How to save the below plot as ``sine_green_border.png`` with green
- color border/edge in the current working directory. The plot is given
- as,
- ::
- x = linspace(-5*pi,5*pi,200)
- plot(x,sin(x),linewidth=2)
- legend(['sin(x)'])
-
- a. ``savefig('sine_green_border.png',bordercolor='green')``
- #. ``savefig('sine_green_border.png',facecolor='green')``
- #. ``savefig('sine_green_border.png',edgecolor='green')``
- #. ``savefig('/sine_green_border.png',bordercolor='green')``
-
-Answer: savefig('sine_green_border.png',edgecolor='green')
-
-8. Given the below code snippet, what does it do?
- ::
- x = linspace(-5*pi,5*pi,200)
- plot(x,sin(x),linewidth=2)
- legend(['sin(x)'])
- savefig('sine.png',format='pdf',papertype='a4')
-
- a. Save the sine plot in file sine.png as a pdf file in page-size
- A4 and saves it into the current working directory
- #. Save the sine plot in file sine.png.pdf in page-size A4 into the
- current working directory.
- #. Save the sine plot in a file sine.png in png format with
- page-size A4 in the current working directory overriding the
- format argument
- #. Error in filename and format mismatch.
-
-Answer: Save the sine plot in file sine.png as a pdf file in page-size
- A4 and saves it into the current working directory
-
-.. #[Puneeth: Good questions, but can we use it in quiz? most of it
-.. has not been taught in the tutorial.]

-Larger Questions
-----------------
-
-.. A minimum of 2 questions here (along with answers)
-
-1. Plot a cosine plot from -2pi to 2pi in green color taking 300
- points. Title the plot as 'Cosine plot' and the legend plot with
- 'cos(x)'. And save the plot as a pdf file with the filename
- cosine_plot.
-
-2. Plot tan(x) where x varies from -4pi to 4pi in red color taking 600
- points. Title the plot as 'Tan plot' and the legend plot with
- 'tan(x)'. And save the plot as a svg file with the filename
- tangent_plot.
