This is an example of a normalized stacked bar chart using data which contains crop yields over different regions and different years in the 1930s.

import altair as alt
from vega_datasets import data

source = data.barley()

alt.Chart(source).mark_bar().encode(
    x=alt.X('sum(yield)', stack="normalize"),
    y='variety',
    color='site'
)
