Highcharts network graph custom link labels

Question

i'm trying to implement a network graph, and in my case the edges must be labeld. For example, i'm fetching data like this

[{from: "A", to: "B", "label":"text1"},{from: "B", to: "C", "label": "text2"}]

so in the graph it must be like this: A-----text1------B--------text2--------C

I've read the docs and there's the linkFormatter that can help me do this but i can't figure it out. I've tried to memic this question's answer highchart network network-graph that shows label on tooltip not the edges. Can please someone help me !!

Answer 1

Use linkFormat or linkFormatter with the correct reference to the property, for example:

    series: [{
        ...,
        dataLabels: {
            enabled: true,
            allowOverlap: true,
            linkFormat: '{point.label}'
        },
    }]
