Highcharts：如何在angularjs控制器中设置yAxis最大值

Question

i'm trying to get yaxis max values..

javascript : chart.yAxis[0].max;

when i try in angularjs as it has slightly different properties :

Highcharts.charts[0].yAxis[0].max gives undefined,
Highcharts.charts[0].yAxis[0].getExtremes.max gives undefined.

is there any way to get the max value inside angularjs controller?

Answer 1

getExtremes is function, not object. You have to call it to obtain extremes.

 var max = chart.yAxis[0].getExtremes().max;
