每件事都很好。图表正在创建等等，但唯一的问题是图表没有动态变化，即我认为图表中的加载事件：{}没有执行或者因为它甚至没有登录控制台。请帮助我。同样的事情是在Here

运行

Answer 1

尝试在更新数据后重新绘制图表。

load: function() {

    // set up the updating of the chart each second
    var series = this.series[0];
    var chart = this;
    setInterval(function() {
        var x = (new Date()).getTime(), // current time
            y = Math.random();
        series.addPoint([x, y], true, true);
        chart.redraw();
        console.log(x + y);
    }, 1000);
}

它看起来像是highcharts-ng中的一个错误。请参阅相关主题：https://github.com/pablojim/highcharts-ng/search?q=load&type=Issues&utf8=%E2%9C%93
