在Plotly，Python中更改图形颜色

Question

就像我们可以使用color属性在matplotlib中更改绘制的图形的颜色一样，有没有任何方法可以在绘图中更改图形的颜色？。

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
