Vistasplotly js colorscale for errorbars
I want to plot the scattered data with a colorscale and the errorbars should have the same colorscale.
I found answers for plotly R (How do you make plotly error bars follow a colorscale?), but I can't translate it to js. Also using the name attribute for this seems strange to me.
Here is a minimal example (https://jsfiddle.net/ztqoemkd/1)
var trace1 = {
type: 'scatter',
mode: 'markers',
y: [2, 1, 3],
marker: {
size: 20,
color: [1, 2, 3],
showscale: true
},
error_y: {
type:'data',
array: [0.5, 0.7, 0.5],
color: [1, 2, 3]
}
}
Plotly.newPlot('myDiv', [trace1])<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>
<div id="myDiv"></div>1 Respuestas

I still don't know, if can be done self consistently with plotly itself.
At least, I could now develop this work around with d3:
// get colors from data points
rgbs = Plotly.d3.selectAll('.points .point').data().map(d => d.mcc)
// apply colors to errorbars
Plotly.d3.selectAll('.yerror').style('stroke', (d,i) => rgbs[i])
Here is the full demo:

and the output is
Note 1: After zooming, the errorbars are again black.
Note 2: It does not work for scattergl.
Edit 1: To keep the colors while zooming, the work around can be attached to plotly_relayout (see https://jsfiddle.net/9s64y5cv).
