Learn Seaborn Introduction
Plotting Aggregates
Recall our gradebook from the previous exercise:
| student | assignment_name | grade |
|---|---|---|
| Amy | Assignment 1 | 75 |
| Amy | Assignment 2 | 82 |
| Bob | Assignment 1 | 99 |
| Bob | Assignment 2 | 90 |
| Chris | Assignment 1 | 72 |
| Chris | Assignment 2 | 66 |
| … | … | … |
Suppose this data is stored in a Pandas DataFrame called df.
The same Seaborn command that you previously learned (sns.barplot()) will plot this data in a bar plot and automatically aggregate the data:
In the example above, Seaborn will aggregate grades by student, and plot the average grade for each student.
Instructions
1.
Use Seaborn to plot the average grade for each assignment. Take a look at gradebook.csv for the column names.
2.
Use plt.show() to display the graph.
