Рисую простую диаграмму на Python
Вот собственно сам код:
import pandas as pd
import altair as alt
df = pd.read_excel('Sample - Superstore.xls', index_col=0)
df2 = df.groupby('Region').sum()
df2 = df2.reset_index(level=0)
bars = alt.Chart(df2).mark_bar().encode(
alt.X('Region:N', sort='-y'),
alt.Y('Sales:Q'),
color=alt.condition( alt.datum.Region == 'West', # If the year is 1810 this test returns True,
alt.value('orange'), # which sets the bar orange.
alt.value('steelblue'))
)
text = bars.mark_text(
align='left',
baseline='middle',
dx=11 # Nudges text to right so it doesn't appear on top of the bar
).encode(
text='mean(Sales):Q'
)
(bars + text).properties(height=300)
