Highcharts:Style Zero Y值

Question

我有一个折线图,其中Y值为-10到+60.我想将y = 0线的样式设置为从其他网格线中脱颖而出.这可能吗？谢谢.

看一下yAxis中的plotLines API ...

示例... http://jsfiddle.net/48dUL/

$(function () {
var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container'
    },
    xAxis: { 
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
    },
            yAxis: { 
        plotLines: [{
            color: '#C0C0C0',
            width: 5,
            value: 0
        }]
    },

    series: [{
        data: [-29.9, -71.5, -106.4, -129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
    }]
});

});
