Add marker.nancolor

[gilles-crealp]

When you set a marker.color array with null values, these markers are black.

Shouldn't they be the same color as the line?

Reading from line:

plotly.js/src/components/colorscale/make_color_scale_func.js

Line 72 in 8c3580f

else return Color.defaultLine;

this is the intended behavior. Granted, you can make a case that this behavior isn't optimal. But we won't consider changing it until v2.

Sad to read that there is no way to set it up to the auto-color of the line...

@alexcjohnson Nice, so I'm reopening this issue. 😉

Is there any update on this feature request?

[nicolaskruchten]

It's a good feature and we'd love to have it in the library but it's not on anyone's roadmap at the moment as far as I know. That said, we as maintainers would be happy to help someone from the community to implement it in Plotly.js, or to accept sponsorship to get it on to our short-term roadmap :)

Hi - this issue has been sitting for a while, so as part of our effort to tidy up our public repositories I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our stack. Cheers - @gvwilson
