막대그래프

import numpy as np
import pandas as pd

df = pd.DataFrame(np.random.rand(10, 2), columns=['A', 'B'])
df.head()

 

import plotly.graph_objects as go
fig = go.Figure()
fig.add_trace(
    go.Bar(
        x=df.index, y=df['A'], name='A', text=df['A'], textposition='auto'
    )
)
fig.add_trace(
    go.Bar(
        x=df.index, y=df['B'], name='B', text=df['B'], textposition='auto'
    )
