更改图中的图形颜色，Python

Question

就像我们可以使用matplotlib使用color属性更改绘制图的颜色，是否有任何方法可以在 plotly 中更改图形的颜色？ 。

Answer 1

import plotly.graph_objects as go
import numpy as np

x = np.linspace(-np.pi, np.pi)
y = np.cos(x)

# this will create a blue line
fig = go.Figure([
    go.Scatter(x=x, y=y)
])
# to modify the figure after it has been created,
# explore fig.data and target the appropriate attribute
fig.data[0].line.color="red"
fig
