這是我的代碼：import plotly.graph_objects as gofig = go.Figure()fig.add_trace(go.Bar( name='Group 1', x=['Var 1', 'Var 2', 'Var 3'], y=[3, 6, 4], error_y=dict(type='data', array=[1, 0.5, 1.5]), width=0.15))fig.add_trace(go.Bar( name='Group 2', x=['Var 1', 'Var 2', 'Var 3'], y=[4, 7, 3], error_y=dict(type='data', array=[0.5, 1, 2]), width=0.15))fig.update_layout(barmode='group')fig.show()輸出：我讀過這篇文章，但來自的代碼似乎已貶值并且不起作用。問題：如何設置圖的背景色和網格線的顏色？

這應該有幫助
import plotly.graph_objects as go
from plotly.graph_objects import Layout
# Set layout with background color you want (rgba values)
# This one is for white background
layout = Layout(plot_bgcolor='rgba(0,0,0,0)')
# Use that layout here
fig = go.Figure(layout=layout)
fig.add_trace(go.Bar(
name='Group 1',
x=['Var 1', 'Var 2', 'Var 3'], y=[3, 6, 4],
error_y=dict(type='data', array=[1, 0.5, 1.5]),
width=0.15
))
fig.add_trace(go.Bar(
name='Group 2',
x=['Var 1', 'Var 2', 'Var 3'], y=[4, 7, 3],
error_y=dict(type='data', array=[0.5, 1, 2]),
width=0.15
))
fig.update_layout(barmode='group')
# Change grid color and axis colors
fig.update_xaxes(showline=True, linewidth=2, linecolor='black', gridcolor='Red')
fig.update_yaxes(showline=True, linewidth=2, linecolor='black', gridcolor='Red')
fig.show()
