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.


When using multiple axes, align the thresholds. When this is true, other ticks will also be aligned.

Note that for line series and some other series types, the threshold option is set to null by default. This will in turn cause their y-axis to not have a threshold. In order to avoid that, set the series threshold to 0 or another number.

If startOnTick or endOnTick in the axis options are set to false, or if the axis is logarithmic, the threshold will not be aligned.
