💡 Hint

Common Mistakes

Using 'plot' instead of 'pyplot'.

Using 'charts' or 'graph' which are not valid matplotlib modules.

The matplotlib.pyplot module is imported as plt to create plots.

2fill in blank

medium

Complete the code to create a list of x values from 0 to 4.

Matplotlib

x = [[1] for i in range(5)]

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

💡 Hint

Common Mistakes

Multiplying or adding to 'i' changes the sequence.

Using 'i-1' results in negative numbers.

Using 'i' directly creates a list [0, 1, 2, 3, 4].

3fill in blank

hard

Fix the error in the code to fill the area between y1 and y2.

Matplotlib

plt.fill_between(x, y1, [1])

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

Cx

Dy1

💡 Hint

Common Mistakes

Using y3 which may not be defined.

Using x instead of a y array.

Repeating y1 as both y arrays.

The fill_between function needs y2 as the second y-value array to fill between y1 and y2.

4fill in blank

hard

Fill both blanks to create y1 and y2 lists for the area chart.

Matplotlib

y1 = [i[1]2 for i in x]
y2 = [i[2]1 for i in x]

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

💡 Hint

Common Mistakes

Using subtraction or integer division instead of multiplication or addition.

Mixing up the operators for y1 and y2.

y1 is each x value multiplied by 2, y2 is each x value plus 1.

5fill in blank

hard

Fill all three blanks to plot the area chart with labels and show it.

Matplotlib

plt.fill_between(x, y1, y2, color='skyblue', alpha=[1])
plt.title('[2]')
plt.show()  # Display the [3]

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

💡 Hint

Common Mistakes

Using alpha values outside 0-1 range.

Forgetting to call plt.show() to display the chart.

Setting title to something unrelated.

Alpha controls transparency, title sets the chart title, and plt.show() displays the plot.
