Facet Grids

What are facet grids?

Section titled “What are facet grids?”

Facet grids create small multiples:

  • The same plot repeated for different subgroups
  • Helps compare patterns across segments

Examples:

  • Distribution by gender
  • Trend by region
  • Relationship by category

One category maps to columns, another (optional) maps to rows, and the same plot type is repeated in every cell.

Facet with displot

Section titled “Facet with displot”
Facet distribution
import seaborn as sns
 
tips = sns.load_dataset("tips")
 
sns.displot(data=tips, x="total_bill", col="time", bins=20, kde=True)

Facet with relplot

Section titled “Facet with relplot”
Facet relationship
import seaborn as sns
 
tips = sns.load_dataset("tips")
 
sns.relplot(data=tips, x="total_bill", y="tip", col="time", hue="sex")

Using FacetGrid directly

Section titled “Using FacetGrid directly”
FacetGrid
import seaborn as sns
import matplotlib.pyplot as plt
 
tips = sns.load_dataset("tips")
 
g = sns.FacetGrid(tips, col="time", row="sex")
g.map_dataframe(sns.scatterplot, x="total_bill", y="tip")
 
plt.tight_layout()

Visualize it

Section titled “Visualize it”

Each small panel is the same chart type, just filtered to one combination of row/column categories — easy to compare shapes side by side:

Each cell repeats the same chart type for one row/column combination, making side-by-side comparison easy.

Tips

Section titled “Tips”
  • Facets can get crowded—keep category counts small.
  • Facets are excellent for storytelling and comparisons.
