JS API Reference

Welcome to the Highcharts JS 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.

xAxis.max

The maximum value of the axis. If null, the max value is automatically calculated.

If the endOnTick option is true, the max value might be rounded up.

If a tickAmount is set, the axis may be extended beyond the set max in order to reach the given number of ticks. The same may happen in a chart with multiple axes, determined by chart. alignTicks, where a tickAmount is applied internally.
