Plotting multiple lines in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to plot two lines on the same graph using matplotlib.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3]
y1 = [2, 4, 6]
y2 = [1, 3, 5]
plt.plot(x, y1)
plt.[1](x, y2)
plt.show()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using plt.scatter or plt.bar instead of plt.plot for lines.

Forgetting to call plt.plot for the second line.

Use plt.plot to plot lines. Here, plt.plot(x, y2) adds the second line.

2fill in blank

medium

Complete the code to add labels to each line in the plot.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3]
y1 = [2, 4, 6]
y2 = [1, 3, 5]
plt.plot(x, y1, label='Line 1')
plt.plot(x, y2, [1]='Line 2')
plt.legend()
plt.show()

Atitle

Blabel

Cxlabel

Dylabel

💡 Hint

Common Mistakes

Using 'title' or 'xlabel' instead of 'label' for line names.

Forgetting to call plt.legend() to display labels.

The label argument names each line for the legend.

3fill in blank

hard

Fix the error in the code to plot multiple lines with different colors.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3]
y1 = [2, 4, 6]
y2 = [1, 3, 5]
plt.plot(x, y1, color='red')
plt.plot(x, y2, color='[1]')
plt.show()

Drag options to blanks, or click blank then click option'

B3

Cblue

Dgreenish

💡 Hint

Common Mistakes

Using invalid color names or numbers for the color argument.

Forgetting quotes around color names.

The color argument must be a valid color name like 'blue'. '3' or 'greenish' are invalid.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps each x to its y1 squared, but only if y1 is greater than 3.

Matplotlib

result = {x: y1[1]2 for x, y1 in zip(x, y1) if y1 [2] 3}

Drag options to blanks, or click blank then click option'

B>

C<

D*

💡 Hint

Common Mistakes

Using '*' instead of '**' for power.

Using '<' instead of '>' in the condition.

Use ** for power and > to filter values greater than 3.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps each line label to the sum of its y values if the sum is greater than 5.

Matplotlib

data = {'Line 1': y1, 'Line 2': y2}
result = [1]: sum([2]) for [1], [2] in data.items() if sum([2]) > 5}

Drag options to blanks, or click blank then click option'

Alabel

Bvalues

Cy

Dline

💡 Hint

Common Mistakes

Using different variable names inconsistently.

Not using the variable names from the options pool.

Use line for the key variable and values for the list of y values.
