100% barchart without calculating?

[marvy]

Is it possible to create the same 100% bar chart without recalculating the values in advance? If I check out a label in the plot, the remaining values should add up to 100%.

import pandas as pd
import plotly.express as px
data = {‘val1’: [10, 200, 55],
‘val2’: [90, 200, 55]}
df = pd.DataFrame(data, index=[‘a’, ‘b’, ‘c’])
df= df.apply(lambda x: round(x * 100 / x.sum(), 2), axis=1)
melted_df = pd.melt(df.reset_index(), id_vars=‘index’, var_name=‘item’, value_name=‘value’)
fig = px.bar(
melted_df,
x=‘index’,
y=‘value’,
color=‘item’,
barmode=‘stack’,
title=‘100% chart’,
)
fig.show()

Hey @marvy, not much has changed in the meantime…

Plotly express :100% stacked barchart

I’m trying to make a 100% stacked barchart. Is this possible in plotly or should I adapt the dataframe? import pandas as pd import plotly.express as px df = pd.DataFrame({"DateTime": pd.date_range(start="2022-01-01", end="2022-01-10")}) df["A"] = np.random.randint(0, 10, size=len(df)) df["B"] = np.random.randint(0, 5, size=len(df)) fig = px.bar(df, x='DateTime', y=['A','B'],title="Stacked barchart 100%",barmode='relative') fig.update_layout(legend_title="Legende") fig.show()
