Subplots maken met col en row

In eerdere oefeningen zagen we dat studenten met meer afwezigheden ("absences") gemiddeld een lagere eindscore ("G3") hebben. Geldt die relatie ongeacht hoeveel tijd studenten elke week studeren?

Om dit te onderzoeken, bekijken we het verband tussen het aantal afwezigheden van een student op school en zijn/haar eindcijfer in de cursus, en maken we aparte subplots op basis van de wekelijkse studietijd van elke student ("study_time").

Seaborn is geïmporteerd als sns en matplotlib.pyplot is geïmporteerd als plt.

# Change to use relplot() instead of scatterplot()
sns.scatterplot(x="absences", y="G3", 
                data=student_data)

What is Seaborn, and when should you use it? In this chapter, you will find out! Plus, you will learn how to create scatter plots and count plots with both lists of data and pandas DataFrames. You will also be introduced to one of the big advantages of using Seaborn - the ability to easily add a third variable to your plots by using color to represent different subgroups.

Exercise 1: Introduction to Seaborn Exercise 2: Making a scatter plot with lists Exercise 3: Making a count plot with a list Exercise 4: Using pandas with Seaborn Exercise 5: "Tidy" vs. "untidy" data Exercise 6: Making a count plot with a DataFrame Exercise 7: Adding a third variable with hue Exercise 8: Hue and scatter plots Exercise 9: Hue and count plots

In this chapter, you will create and customize plots that visualize the relationship between two quantitative variables. To do this, you will use scatter plots and line plots to explore how the level of air pollution in a city changes over the course of a day and how horsepower relates to fuel efficiency in cars. You will also see another big advantage of using Seaborn - the ability to easily create subplots in a single figure!

Categorical variables are present in nearly every dataset, but they are especially prominent in survey data. In this chapter, you will learn how to create and customize categorical plots such as box plots, bar plots, count plots, and point plots. Along the way, you will explore survey data from young people about their interests, students about their study habits, and adult men about their feelings about masculinity.

In this final chapter, you will learn how to add informative plot titles and axis labels, which are one of the most important parts of any data visualization! You will also learn how to customize the style of your visualizations in order to more quickly orient your audience to the key takeaways. Then, you will put everything you have learned together for the final exercises of the course!
