Plotly:如何根据条件对两行之间的填充进行着色？

import plotly.graph_objects as go

# 创建线图
fig = go.Figure()

# 添加数据
x = [1, 2, 3, 4, 5]
y1 = [1, 3, 2, 4, 3]
y2 = [2, 4, 3, 5, 4]

fig.add_trace(go.Scatter(
    x=x,
    y=y1,
    fill='tozeroy',
    mode='lines',
    name='Line 1'
))

fig.add_trace(go.Scatter(
    x=x,
    y=y2,
    fill='tozeroy',
    mode='lines',
    name='Line 2'
))

# 根据条件设置填充颜色
for i in range(len(x) - 1):
    if y1[i] > y2[i]:
        fill_color = 'green'
    else:
        fill_color = 'red'
    fig.update_traces(fillcolor=fill_color, selector=dict(type='scatter', fill='tozeroy', fillcolor='rgba(0,0,0,0)'))

# 自定义其他样式选项
fig.update_layout(
    title='Fill between two lines with conditional coloring',
    xaxis_title='X-axis',
    yaxis_title='Y-axis'
)

# 展示图表
fig.show()
