react() and plot_bgcolor

[nicolaskruchten]

This is a CodePen https://codepen.io/nicolaskruchten/pen/pojdmaX?editors=0010 that illustrates the issue outlined in https://community.plotly.com/t/changing-the-background-colour-of-a-graph/29246/8 and logged in Dash as plotly/dash#1107

Edit: the newPlot behaviour is correct and the react behaviour is not.

@alexcjohnson is it intended that in the second figure straight off of newPlot that plot_bgcolor: "red" does nothing?

[alexcjohnson]

plot_bgcolor only applies to cartesian subplots AFAIK. All the other subplot types have their own subplot container objects (in this case scene) with their own bgcolor attributes. Might have been a good idea for these to inherit from plot_bgcolor but I think that ship has sailed.

If you add scene: {bgcolor: "green", domain: {x: [0,0.7]}} to the second layout you'll see both green and blue after react-ing from 0 to 1

OK re cartesian subplots... Does this make the current behaviour "correct" or do we agree that the blue should be cleared when I react from scatter to scatter3d ?

[alexcjohnson]

Oh definitely a bug

[nicolaskruchten]

So what do you think the correct behaviour should be? on newPlot2 should there be a red background, or should the background go to white on react2?

[alexcjohnson]

There’s no Cartesian subplot so there should be no red, just white.

[nicolaskruchten]

OK, so the newPlot behaviour is correct and the react behaviour is not.

hi

from what I can tell, it is not possible to update sunburst background color?

Thanks
