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.


In an ordinal axis, the points are equally spaced in the chart regardless of the actual time or x distance between them. This means that missing data periods (e.g. nights or weekends for a stock chart) will not take up space in the chart. Having ordinal: false will show any gaps created by the gapSize setting proportionate to their duration.

In stock charts the X axis is ordinal by default, unless the boost module is used and at least one of the series' data length exceeds the boostThreshold.

For an ordinal axis, minPadding and maxPadding are ignored. Use overscroll instead.
