Hi, I am using the plotly_dark template and when I plot an animated graph with a background colour the tick marks seem to disappear even when I attempt to force them as in the code below. Is there something else I need to do in order to get the tick marks to show up?
fig['layout']['sliders'][0]['minorticklen'] = 2
fig['layout']['sliders'][0]['ticklen'] = 5
fig['layout']['sliders'][0]['tickcolor'] = 'grey'
fig['layout']['sliders'][0]['font']['color'] = 'grey'
Remove template="plotly_dark", set in layout paper_bgcolor="black",
and
fig[âlayoutâ][âslidersâ][0][âtickcolorâ] = ârgb(230,230,230â #or ârgb(235,235,235)â
fig[âlayoutâ][âslidersâ][0][âfontâ][âcolorâ] = ârgb(230,230,230â
Worked! Thanks. Is there a good reference for instances like this where we need to dig around âunder the hoodâ a bit more than standard configurations allow for?
@doogra
I donât think that such a reference can be found among Plotly tutorials, that explicitly tells you how to fix such an issue. Itâs the long experience with plotly plots (7 years) that helped me find a solution.
I recently wrote this doc, which should go some ways toward giving you a way to bootstrap your understanding of the depths of the figure structure 
Introspecting Figures | Python | Plotly ⌠itâs an extension of this more high-level guide: The Figure Data Structure | Python | Plotly
I should add that all the slider-related reference has been collected into its own page also: layout.sliders | Python | Plotly
Hey @nicolaskruchten
The Introspecting Figures doc is fantastic. Was there an announcement when this came out?
Even if there was, it might be worth promoting it again and give it top billing. 
Iâm so glad you find it useful! It was announced when we released Plotly.py 4.10 I think⌠If you want to make a new post explaining how itâs useful for you, I think that would be fantastic
