Welcome to the Highcharts Stock JS (highstock) Options Reference

These pages outline the chart configuration options, and the methods and properties of Highcharts objects.

Feel free to search this API through the search bar or the navigation tree in the sidebar.


Trendline (linear regression) fits a straight line to the selected data using a method called the Sum Of Least Squares. This series requires the linkedTo option to be set.

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