Anirudh is trying to write a code to plot line graph shown in the figure below. Help him fill in the blanks in the code and get the desired output.

import matplotlib.pyplot as plt             # statement 1
x = [1, 2, 3]                               # statement 2
y = [2, 4, 1]                               # Statement 3
plt.plot(x, y, color = 'g')                 # statement 4
...............                             # statement 5
...............                             # statement 6
# giving a title to graph
plt. ............... ('My first graph!')    # statement 7
# Function to show the plot 
...............                             # statement 8

(i) Which of the above statements is responsible for plotting the values on canvas?

1. Statement 8
2. Statement 4
3. Statement 1
4. None of these

(ii) Statements 5 & 6 are used to give names to X-axis and Y-axis as shown in Fig.1. Which of the following can fill those two gaps?

1.

plt.xlabel('X - axis') 
plt.ylabel('Y - axis')

2.

plt.xtitle('x - axis')
plt.ytitle('y - axis')

3.

plt.xlable('x - axis')
pit.ylable('x - axis') 

4.

plt.xlabel('x axis')
plt.ylabel('y axis')

(iii) Raman has executed code with first 7 statements but no output is displayed. Which of the following statements will display the graph?

1. plt.display()
2. plt.show()
3. matplotlib.pyplot.display()
4. Both (b) & (c)

(iv) The number of markers in the above line chart are:

1. Zero
2. Three
3. Infinite
4. Not defined

(v) Which of the following methods will result in displaying 'My first graph!' in the above graph?

1. legend()
2. label()
3. title()
4. Both (a) & (c)

Plot a line chart for depicting the population for the last 5 years as per the specifications given below:

• plt.title("My Title") will add a title "My Title" to your plot.

• plt.xlabel("Year") will add a label "Year" to your X-axis.

• plt.ylabel("Population") will add a label "Population" to your Y-axis.

• plt.yticks([1, 2, 3, 4, 5]) set the numbers on the Y-axis to be 1, 2, 3, 4, 5. Pass it and label as a second argument. For example, if we use this code plt.yticks([1, 2, 3, 4, 5], ["1M", "2M", "3M", "4M", "5M"]), it will set the labels 1M, 2M, 3M, 4M, 5M on the Y-axis.

• plt.xticks() — works the same as plt.yticks(), but for the X-axis.

What do you mean by pyplot?

How many types of graphs are plotted using pyplot?
