Stacked area chart in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to import the correct plotting library for creating a stacked area chart.

Matplotlib

import [1] as plt

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

Apandas

Cseaborn

Dnumpy

💡 Hint

Common Mistakes

Importing 'numpy' or 'pandas' instead of 'matplotlib.pyplot'.

Using 'seaborn' which is a different plotting library.

We use matplotlib.pyplot to create plots including stacked area charts.

2fill in blank

medium

Complete the code to define the x-axis values for the stacked area chart.

Matplotlib

x = [1](1, 6)

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

Arange

Bnp.array

Clist

Dpd.Series

💡 Hint

Common Mistakes

Using list without specifying the sequence.

Using np.array without importing numpy.

The range function creates a sequence of numbers, perfect for x-axis values.

3fill in blank

hard

Fix the error in the code to correctly plot the stacked area chart using plt.stackplot.

Matplotlib

plt.stackplot(x, y1, y2, [1]=labels)
plt.show()

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

Alabels

Blegend

Ctitle

Dlabel

💡 Hint

Common Mistakes

Using 'label' instead of 'labels' causes the legend not to show.

Using 'legend' as a parameter causes an error.

The correct keyword argument for naming areas in stackplot is labels but it must be passed as labels=. However, the parameter is labels plural, so the correct answer is labels.

But since the options have 'labels' and 'label', the correct keyword is labels.

4fill in blank

hard

Fill both blanks to create a stacked area chart with a legend and axis labels.

Matplotlib

plt.stackplot(x, y1, y2, [1]=labels)
plt.[2]('X axis')
plt.show()

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

Alabels

Bxlabel

Cylabel

Dlegend

💡 Hint

Common Mistakes

Using 'label' instead of 'labels' in stackplot.

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

Use labels to name the areas in the stackplot, and xlabel to label the x-axis.

5fill in blank

hard

Fill all three blanks to create a stacked area chart with labels, y-axis label, and a legend.

Matplotlib

plt.stackplot(x, y1, y2, [1]=labels)
plt.[2]('Y axis')
plt.[3]()

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

Alabels

Bylabel

Clegend

Dtitle

💡 Hint

Common Mistakes

Forgetting to call legend() to display the legend.

Using 'label' instead of 'labels' in stackplot.

Use labels to name the areas, ylabel to label the y-axis, and legend() to show the legend.
