Error bar plots in Matplotlib - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create an error bar plot with y-error.

Matplotlib

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [2, 3, 5, 7]
yerr = [0.2, 0.3, 0.1, 0.4]

plt.errorbar(x, y, [1]=yerr)
plt.show()

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

💡 Hint

Common Mistakes

Using 'xerr' instead of 'yerr' for vertical error bars.

Passing the error values as 'x' or 'y' parameters.

The yerr parameter specifies the error bars for the y-values in plt.errorbar.

2fill in blank

medium

Complete the code to add marker style 'o' to the error bar plot.

Matplotlib

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [2, 3, 5, 7]
yerr = [0.2, 0.3, 0.1, 0.4]

plt.errorbar(x, y, yerr=yerr, [1]='o')
plt.show()

💡 Hint

Common Mistakes

Using 'linestyle' to try to set markers.

Confusing 'color' with marker style.

The marker parameter sets the style of the points in the plot, such as circles ('o').

3fill in blank

hard

Fix the error in the code to correctly plot horizontal error bars.

Matplotlib

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [2, 3, 5, 7]
xerr = [0.1, 0.2, 0.1, 0.3]

plt.errorbar(x, y, [1]=xerr)
plt.show()

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

💡 Hint

Common Mistakes

Using 'yerr' for horizontal error bars.

Passing error values as 'x' or 'y' parameters.

To add horizontal error bars, use the xerr parameter in plt.errorbar.

4fill in blank

hard

Fill both blanks to create an error bar plot with red color and dashed line style.

Matplotlib

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [2, 3, 5, 7]
yerr = [0.2, 0.3, 0.1, 0.4]

plt.errorbar(x, y, yerr=yerr, [1]=[2])
plt.show()

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

💡 Hint

Common Mistakes

Swapping color and linestyle parameters.

Using color names without quotes.

The color parameter sets the color of the plot, and '--' is the dashed line style.

5fill in blank

hard

Fill all three blanks to create an error bar plot with blue color, circle markers, and dotted line style.

Matplotlib

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [2, 3, 5, 7]
yerr = [0.2, 0.3, 0.1, 0.4]

plt.errorbar(x, y, yerr=yerr, [1]=[2], [3]='o')
plt.show()

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

💡 Hint

Common Mistakes

Using color values without quotes.

Confusing linestyle symbols.

The color parameter sets the line color, 'blue' is the color value, and linestyle with ':' creates a dotted line. The marker='o' adds circle markers.
