Bug using the underscore notation for annotation attributes, coupled with buttons #4007
Description
Hi, I just had trouble with the following example:
fig.update_layout(
updatemenus=[
dict(
type="buttons",
buttons=[
dict(
label="All",
method="update",
args=[
{"visible": [True] * 9}, # show all traces
{
"annotations": [inner_annotation]
},
],
),
],
)
]
)
Everything works fine on the figure load, however, clicking on the button would change the font_size of my annotation back to default, whereas I set it on 16.
inner_annotation = dict(
...
font_size=16,
)
After some tests I figured out changing the syntax to
inner_annotation = dict(
...
font={"size": 16},
)
resolved the issue.
