A treegraph series is a diagram, which shows a relation between ancestors and descendants with a clear parent - child relation. The best examples of the dataStructures, which best reflect this chart are e.g. genealogy tree or directory structure.

In TypeScript the type option must always be set.

Configuration options for the series are given in three levels:

  1. Options for all series in a chart are defined in the plotOptions.series object.
  2. Options for all treegraph series are defined in plotOptions.treegraph.
  3. Options for one single series are given in the series instance array.
Highcharts.chart('container', {
    plotOptions: {
        series: {
            // general options for all series
        treegraph: {
            // shared options for all treegraph series
    series: [{
        // specific options for this series instance
        type: 'treegraph'
