Python 中的 Altair 图表：如何删除“HConcatChart”的复合图表边框

Question

import altair as alt
from vega_datasets import data

iris = data.iris.url

chart1 = alt.Chart(iris).mark_point().encode(
    x='petalLength:Q',
    y='petalWidth:Q',
    color='species:N'
).properties(
    height=300,
    width=300
)

chart2 = alt.Chart(iris).mark_bar().encode(
    x='count()',
    y=alt.Y('petalWidth:Q', bin=alt.Bin(maxbins=30)),
    color='species:N'
).properties(
    height=300,
    width=100
)

alt.hconcat(chart1, chart2).ViewConfig(strokeWidth = 0)

Is there any way to make the border of these two horizontal charts disabled? The.config_view is not available for compound charts.

Thanks.

You can use the .configure_view() method on the concatenated chart to remove the view border in each subchart:

import altair as alt
from vega_datasets import data

iris = data.iris.url

chart1 = alt.Chart(iris).mark_point().encode(
    x='petalLength:Q',
    y='petalWidth:Q',
    color='species:N'
).properties(
    height=300,
    width=300
)

chart2 = alt.Chart(iris).mark_bar().encode(
    x='count()',
    y=alt.Y('petalWidth:Q', bin=alt.Bin(maxbins=30)),
    color='species:N'
).properties(
    height=300,
    width=100
)

alt.hconcat(chart1, chart2).configure_view(strokeWidth = 0)
