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/demo/line-basic/ here max value is 30. If you disable New York and Tokyo it is 20 and so on.
chart is your chart var.
@Anagio told that it's possible to get it the following way.
This way you can get the data values and the tick values.
The data values are the values from your series, while the tick values are the values from chart lines.
This information is directly accessible from a
Axis object. For example:
var chart = $('#container').highcharts(); var axisMax = chart.yAxis.max; // Max of the axis var dataMax = chart.yAxis.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
