Question

How can I get the max value of a y axis at highcharts?

i.e. http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts

Answer 1

This information is directly accessible from a Axis object. For example:

var chart = $('#container').highcharts();
var axisMax = chart.yAxis[0].max; // Max of the axis
var dataMax = chart.yAxis[0].dataMax; // Max of the data

As mentioned you can use Axis.getExtremes (API) , but the same data is also available as:

• Axis.min: Min of the axis
• Axis.max: Max of the axis
• Axis.dataMin: Min of the data
• Axis.dataMax: Max of the data

And even some historic data if the extremes of the axis has changed:

• Axis.oldMin: The previous min of the axis
• Axis.oldMax: The previous max of the axis
