使用plotly创建略微重叠的条形图

import plotly.graph_objects as go

x = ['A', 'B', 'C', 'D']
y1 = [10, 15, 7, 12]
y2 = [8, 12, 10, 11]

fig = go.Figure()

fig.add_trace(go.Bar(
    x=x,
    y=y1,
    name='Series 1',
    marker_color='blue',
    width=0.4
))

fig.add_trace(go.Bar(
    x=x,
    y=y2,
    name='Series 2',
    marker_color='red',
    width=0.4,
    offset=-0.2
))

fig.update_layout(
    title='略微重叠的条形图',
    xaxis=dict(title='类别'),
    yaxis=dict(title='数值'),
    barmode='group',
    bargap=0.1,
    bargroupgap=0.1
)

fig.show()
