Trellis Scatter Plot

This example shows how to make a trellis scatter plot.

Method syntax

import altair as alt
from vega_datasets import data

source = data.cars()

alt.Chart(source).mark_point().encode(
    x='Horsepower:Q',
    y='Miles_per_Gallon:Q',
    row='Origin:N'
)

Attribute syntax

import altair as alt
from vega_datasets import data

source = data.cars()

alt.Chart(source).mark_point().encode(
    x='Horsepower:Q',
    y='Miles_per_Gallon:Q',
    row='Origin:N'
)
# No channel encoding options are specified in this chart
# so the code is the same as for the method-based syntax.
