（我如何在图上加下划线？

Question

我尝试在使用注释时在文本上加下划线。我使用

添加我的注释

import plotly.graph_objects as go
g = go.FigureWidget(make_subplots(rows=1,cols=1))
g.update_layout(annotations=[dict(text='my text')]) #plus any other parameters

是否有选项（可能在注释字典中？）带有下划线的文本？

谢谢！

Answer 1

string = "These are orange"
myText = string+'<br>'+ '-'*len(string)

简介：

产品编号：
import plotly.graph_objects as go
animals=['giraffes', 'orangutans', 'monkeys']

fig = go.Figure([go.Bar(x=animals, y=[20, 14, 23])])

string = "These are orange"
myText = string+'<br>'+ '-'*len(string)

fig.update_layout(annotations=[dict(x='orangutans',y = 15, text=myText, font=dict(family='Courier New, monospace'))])
fig.show()

打印源：使用help(fig.layout)：

  text
 |                  Sets the text associated with this annotation.
 |                  Plotly uses a subset of HTML tags to do things
 |                  like newline (<br>), bold (<b></b>), italics
 |                  (<i></i>), hyperlinks (<a href='...'></a>).
 |                  Tags <em>, <sup>, <sub> <span> are also
 |                  supported.
