Scatter3d plot_bgcolor not working

[Serzl]

I am trying to set plot color to be white, however it does note seem to be working.

Below is an example setting paper and plot colors to black.
While paper_bgcolor is working plot_bgcolor does not work.

import plotly.graph_objects as go

fig = go.Figure(data=go.Scatter3d(x=[1, 2], y=[1,1], z=[1,1], mode = 'markers'), )

fig.update_layout(autosize = False, width = 2000, height = 1000)

# fig.layout.paper_bgcolor = '#000000'
fig.layout.plot_bgcolor = '#000000'

fig.show()

I have tried multiple configurations, including the following post recommendations. Nothing so far worked.

Would appreciate your help and suggestions.
Even workarounds, like hardcoding plot colors in the python library would work as a temporary solutions for me.

Setting template='plotly_white' does the job:

fig.update_layout(template='plotly_white', autosize = False, width = 1000, height = 500)

But if you want to set another color for the three coordinate planes, then you can define
a function:

def set_bgcolor(bg_color = "rgb(20, 20, 20)",
                grid_color="rgb(150, 150, 150)", 
                zeroline=False):
    return dict(showbackground=True,
                backgroundcolor=bg_color,
                gridcolor=grid_color,
                zeroline=zeroline)

This is its effect, when setting scene axes as follows:

fig = go.Figure(go.Scatter3d(x=[1, 2], y=[1,1], z=[1,1], 
                             mode = 'markers', marker_color="rgb(255, 200, 0)"))
fig.update_scenes(xaxis=set_bgcolor(), 
                  yaxis=set_bgcolor(), 
                  zaxis=set_bgcolor())

When you have questions and no plotly.py issues, please address them on Plotly forum: https://community.plotly.com/, not here.

Ok, I have the same issue in Dash. I've been able to track this down to the following.

The sample code works fine in just Plotly. However, in Dash the plot's bgcolor is always transparent. This makes the paper bgcolor the only one seen.

In Plotly:

In Plotly+Dash:

For a 2d plot the background is a rectangular region, while for a 3d one, the scene consists in three such rectangular regions (three planes). That's why theplot_bgcolor="black" has no effect in the case of 3d plots. It's not an issue, but a natural behaviour!!!
To set a black or any other background color, for a 3d plot, you should define a dict black3dbg , as below:

import plotly.graph_objects as go
import numpy as np
from numpy import pi, sin

black3dbg = dict(
        showbackground = True, 
        backgroundcolor ="rgb(10,10,10)", 
        gridcolor = "rgb(150, 150, 150)",  
        gridwidth=1.5,
        zeroline = False)


x, y = np.meshgrid(np.linspace(-pi/2, pi/2, 100), np.linspace(-pi/2, pi/2, 100))
fig=go.Figure(go.Surface(x=x[0, :], y=y[:, 0], z=np.cos(x+y)*sin(x*y), colorbar_len=0.6))
fig.update_layout(width=600, height=600)
fig.update_scenes(xaxis=black3dbg, 
                  yaxis=black3dbg, 
                  zaxis=black3dbg,
                 camera_eye=dict(x=1.75, y=1.75, z=1))

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for a while, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Alternatively, if it's a request for tech support, please post in our community forum. Thank you - @gvwilson
