Altair distance between bar labels in mark_text

[seblful]

I can't set distances between bar labels in grouped stacked bar_chart

This is how my data looks

This is my code

chart = alt.Chart(chain_and_prices_for_bar, title='Распределение средних цен различных ценовых категорий среди аптечных сетей в разрезе страны производства').mark_bar().encode(
    x=alt.X('category_of_price:N', sort=['Низкая', 'Ниже среднего', 'Средняя', 'Выше среднего', 'Высокая', 'Самая высокая'], title=None, axis=alt.Axis(labelAngle=-45, labelOverlap=False)),
    y=alt.Y('mean_price_of_medicine:Q', axis=alt.Axis(grid=False, title='Суммарная средняя цена'), scale=alt.Scale(domain=[0, 201], bins=[i for i in range(211) if i%10 ==0])),
   header=alt.Header(labelFontSize=11, labelFontStyle='bold')),
    order=alt.Order(
      'is_import', sort='ascending'),
    color=alt.Color('is_import:N', scale=alt.Scale(range=['#96ceb4', '#ffcc5c']),
        legend=alt.Legend(title='Страна производства'))
    ).properties(
        width=100,
        height=600)

chart.configure_title(fontSize=18, anchor='middle', align='center', dy=-10)
    
text = alt.Chart(chain_and_prices_for_bar).mark_text(dy=3, color='black', align='center', baseline='bottom', angle=270).encode(
    x=alt.X('category_of_price:N', sort=['Низкая', 'Ниже среднего', 'Средняя', 'Выше среднего', 'Высокая', 'Самая высокая'], title=None, axis=alt.Axis(labelAngle=-45, labelOverlap=False)),
    y=alt.Y('mean_price_of_medicine:Q'),
    detail='retail_chain:N',
    text=alt.Text('mean_price_of_medicine:Q', format='.2f'))

alt.layer(
    chart, text, data=chain_and_prices_for_bar).facet(
    facet=alt.Column('retail_chain:N', title=None, sort=list_of_top_pharmacies, header=alt.Header(labelFontSize=11, labelFontStyle='bold')),
).configure_view(continuousHeight=200, continuousWidth= 0.5).configure_facet(spacing=0.5)

This is what i got

numbers are overlapping and i need to change it

there aren't right answers, it's not working for grouped stacked bar plot
