1fill in blank

💡 Hint

Common Mistakes

Importing 'matplotlib' directly instead of 'matplotlib.pyplot'.

Using 'import pyplot as plt' without 'matplotlib'.

We import the pyplot module from matplotlib as plt to create plots.

2fill in blank

medium

Complete the code to create two lists of data for histograms.

Matplotlib

data1 = [1, 2, 3, 4, 5]
data2 = [1]

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

A[2, 3, 4, 5, 6]

B[5, 4, 3, 2, 1]

C[1, 1, 2, 2, 3]

D[6, 7, 8, 9, 10]

💡 Hint

Common Mistakes

Using the same list for both data sets.

Using an empty list.

We create a second list of numbers to overlay a second histogram.

3fill in blank

hard

Fix the error in the code to plot the first histogram with 5 bins.

Matplotlib

plt.hist(data1, bins=[1])
plt.show()

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

A'5'

B[5]

Cbins=5

D5

💡 Hint

Common Mistakes

Passing bins as a string like '5'.

Passing bins as a list like [5].

The bins parameter expects an integer, not a string or list.

4fill in blank

hard

Fill both blanks to plot two histograms overlayed with transparency.

Matplotlib

plt.hist(data1, bins=[1], alpha=[2])
plt.hist(data2, bins=5, alpha=0.5)
plt.show()

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

A5

B0.5

C1

D0.8

💡 Hint

Common Mistakes

Using different bins for the two histograms.

Using alpha=1 which hides the histogram underneath.

We use 5 bins and alpha=0.5 for transparency to see both histograms clearly.

5fill in blank

hard

Fill all three blanks to add labels and a legend to the overlayed histograms.

Matplotlib

plt.hist(data1, bins=5, alpha=0.5, label=[1])
plt.hist(data2, bins=5, alpha=0.5, label=[2])
plt.[3]()
plt.show()

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

A"Data 1"

B"Data 2"

Clegend

💡 Hint

Common Mistakes

Not adding labels to histograms.

Using plt.show() instead of plt.legend() to show legend.

Labels name each histogram, and plt.legend() shows the legend on the plot.
