Welcome to the Highcharts JS (highcharts) 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.


If no x values are given for the points in a series, pointInterval defines the interval of the x values. For example, if a series contains one value every decade starting from year 0, set pointInterval to 10. In true datetime axes, the pointInterval is set in milliseconds.

It can be also be combined with pointIntervalUnit to draw irregular time intervals.

If combined with relativeXValue, an x value can be set on each point, and the pointInterval is added x times to the pointStart setting.

Please note that this options applies to the series data, not the interval of the axis ticks, which is independent.
