Highcharts中的动态数据

Highcharts.chart('container', {
    series: [{
        data: [1, 2, 3, 4]
    }]
});

setInterval(function () {
    var chart = Highcharts.charts[0],
        series = chart.series[0],
        x = (new Date()).getTime(),
        y = Math.random();

    series.addPoint([x, y], true, true);
}, 1000);

var chart = Highcharts.chart('container', {
    series: [{
        data: [1, 2, 3, 4]
    }]
});

setInterval(function () {
    var newData = [Math.random()];
    chart.update({
        series: [{
            data: newData
        }]
    });
}, 1000);

var chart = Highcharts.chart('container', {
    series: [{
        data: [1, 2, 3, 4]
    }]
});

setInterval(function () {
    var newData = [Math.random()];
    chart.addSeries({
        data: newData
    });
}, 1000);
