A heatmap is a graphical representation of data where the individual values contained in a matrix are represented as colors.

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