1fill in blank

easy

Complete the code to plot data points with circle markers.

💡 Hint

Common Mistakes

Using 'x' instead of 'o' for circle markers.

The marker 'o' draws circle markers on the data points.

2fill in blank

medium

Complete the code to plot data points with square markers.

Matplotlib

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

Common Mistakes

Using 'd' which is diamond, not square.

The marker 's' draws square markers on the data points.

3fill in blank

hard

Fix the error in the code to plot data points with triangle up markers.

Matplotlib

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

💡 Hint

Common Mistakes

Using 'v' which is triangle down, not up.

The marker '^' draws triangle up markers on the data points.

4fill in blank

hard

Fill both blanks to create a plot with red diamond markers and dashed line style.

Matplotlib

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

💡 Hint

Common Mistakes

Using solid line '-' instead of dashed '--'.

Marker 'd' is diamond, linestyle '--' is dashed line.

5fill in blank

hard

Fill all three blanks to create a plot with green plus markers, dotted line style, and linewidth 2.

Matplotlib

import matplotlib.pyplot as plt
x = [1, 2, 3]
y = [4, 5, 6]
plt.plot(x, y, marker=[1], linestyle=[2], linewidth=[3], color='green')
plt.show()

💡 Hint

Common Mistakes

Using solid line '-' instead of dotted ':'.

Marker '+' draws plus signs, linestyle ':' is dotted, linewidth 2 makes line thicker.
