Question

highCharts曲线图上的y点值,

plotOptions: { spline: { shadow: true, animation: true, lineWidth: 1 }, series: { color: '#00b16a', lineWidth:4, cursor: 'pointer', events: { click: function(event) { alert('如何同时或得当前点Y1轴和y2轴的值因为有两条曲线'); } } } },

Answer 1

简单啦，先获取 x 轴下标，在获取对应下标的 y 轴值就OK了，代码如下：

plotOptions: {
    spline: {
        marker: {
            radius: 4,
            lineColor: '#666666',
            lineWidth: 1
        },
        point: {
            events: {
                click: function(e) {
                    var index = this.x;
                    var result = '';
                    for (var i = 0; i < chart.series.length; i++) {
                        result += chart.series[i].name + ' : ' + chart.series[i].data[index].y;
                        console.log(chart.series[i].data)
                    }
                    console.log(result)
                    alert(result);
                }

            },
        }

    }
},
