Basic plt.plot usage in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to plot a simple line graph of y values.

Matplotlib

import matplotlib.pyplot as plt

y = [1, 3, 2, 4]
plt.[1](y)
plt.show()

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

💡 Hint

Common Mistakes

Using plt.scatter instead of plt.plot for line graphs.

Using plt.bar which creates bar charts, not line plots.

The plt.plot() function draws a line graph connecting the points in the list y.

2fill in blank

medium

Complete the code to plot x and y values as a line graph.

Matplotlib

import matplotlib.pyplot as plt

x = [0, 1, 2, 3]
y = [1, 3, 2, 4]
plt.plot([1], y)
plt.show()

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

C[1, 2, 3]

💡 Hint

Common Mistakes

Passing y twice instead of x and y.

Passing a list of zeros which will plot all points on the y-axis.

The plt.plot() function needs both x and y values to plot points correctly. Here, x is the list of x-coordinates.

3fill in blank

hard

Fix the error in the code to plot x and y values with a red dashed line.

Matplotlib

import matplotlib.pyplot as plt

x = [0, 1, 2, 3]
y = [1, 3, 2, 4]
plt.plot(x, y, [1])
plt.show()

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

A'r--'

B'blue'

C'green'

D'--r'

💡 Hint

Common Mistakes

Using 'blue' or 'green' which are color names but not combined with line style.

Reversing the order as '--r' which is invalid.

The string 'r--' tells matplotlib to plot a red dashed line. The order matters: color first, then line style.

4fill in blank

hard

Fill both blanks to create a plot with x and y values and label the x-axis.

Matplotlib

import matplotlib.pyplot as plt

x = [1, 2, 3]
y = [4, 5, 6]
plt.[1](x, y)
plt.[2]('Time (s)')
plt.show()

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

💡 Hint

Common Mistakes

Using ylabel instead of xlabel for the x-axis label.

Forgetting to plot the data before labeling.

plt.plot() draws the line graph. plt.xlabel() adds a label to the x-axis.

5fill in blank

hard

Fill all three blanks to create a plot with x and y, add a title, and label the y-axis.

Matplotlib

import matplotlib.pyplot as plt

x = [0, 1, 2]
y = [3, 1, 4]
plt.[1](x, y)
plt.[2]('Sample Plot')
plt.[3]('Value')
plt.show()

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

Aplot

Btitle

Cylabel

Dxlabel

💡 Hint

Common Mistakes

Mixing up xlabel and ylabel.

Forgetting to add the title or y-axis label.

plt.plot() draws the line graph, plt.title() adds the plot title, and plt.ylabel() labels the y-axis.
