查看http://www.highcharts.com/demo/pie-donut示例,我看到它yAxis.title.text
设置为“市场份额总百分比”。
这样做的目的是什么?
xAxis
也用于饼图,如果是,用于什么目的?
$('#container').highcharts({
chart: {
type: 'pie'

},

},
yAxis: {
title: {
text: 'Total percent market share'
}
},
plotOptions: {

}
},

return this.y > 5 ? this.point.name : null;
},
