I would like to know if it is possible to put a hover text on the title ? I checked the documentation (here: https://plot.ly/python/reference/#layout-title) and I didn’t find what I want.
I don’t think this is possible yet with Dash. But you could move the title to a Heading and use the excellent Dash Bootstrap component that has tooltips.
Slightly modified from the dbc docs :
import dash_bootstrap_components as dbc
import dash_html_components as html
tooltip = html.Div(
[
html.H1(
[
html.Span(
"My Cool Title", id="tooltip-target"
),
]
),
dbc.Tooltip(
"My Cooler Hover Tooltip",
target="tooltip-target",
),
]
)
