I try to underline text in plotly when using annotations. I add my annotations using
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
Is there an option (in the annotations dict, maybe?) to have underlined text?
Thanks!
Plotly uses a subset of HTML tags to format text like bold '<b></b>'
and italics '<i></i>'
. Alas, '<u></u>'
does not seem to be included at the moment. But linebreak is included, so you could make a little work-around like this:
string = "These are orange"
myText = string+'<br>'+ '-'*len(string)
Plot:
Code:
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()
Plotly source: using 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.
Came here to find an answer, and found a better one from the reply. Since "span" is supported. you can do
string = "These are orange"
myText = "<span style='text-decoration:underline;'>"+string+"</span>"
