Problem with scatter plot if the color vector contains only zeros

plotly.js
1

Hello,

The problem occurs for the scatter plot.
If all values are 0s in the color vector, then the color of dots is orange instead of expected light grey.
As a remark, for the 3D scatter plot it works well.
Thanks!

Can you share a reproducible example?

var trace1 = {
y: [5, 5, 5, 5, 5],
mode: ‘markers’,
marker: {
size: 40,
color: [0, 0, 0, 0, 0]
}
};

var data = [trace1];

var layout = {
title: ‘Scatter Plot with a Color Dimension’
};

Plotly.newPlot(‘myDiv’, data, layout);

Ha. Thanks for bringing this up.

I file a bug report here https://github.com/plotly/plotly.js/issues/1109. I’d recommend subscribe to the issue for the latest development info.

Is there a way to force the color of points to a given color?

Setting marker.color: ['red', 'green', 'blue'] should do the trick.

Thank you for you answer, but I do not understand how this works.
Could you please give me an example related to the use case with the bug above to force setting the 5 points to a grey color?
Thanks!
