Question

下面是图表代码，我的问题是需要使用JSON来获取更新的数据。我不想重新绘制整个图表，而是只绘制蜡烛（添加新蜡烛）。

我想必须有一个循环，通过循环JSON并创建chart.update来逐秒查看新数据？

希望我能用代码解决这个问题！

$.getJSON('/api/v1/public/getcharts?market=BTC-'+coinsymbol, function (data) {

    // split the data set into trading and volume
    var trading = [],
        volume = [],
        dataLength = data.length,
        // set the allowed units for data grouping
        groupingUnits = [[
            'hour',                         // unit name
            [1]                             // allowed multiples
        ], [
            'day',
            [1, 7]
        ]],

        i = 0;


    for (i; i < dataLength; i += 1) {
        trading.push([
            data[i][0], // the date
            data[i][1], // open
            data[i][2], // high
            data[i][3], // low
            data[i][4] // close
        ]);

        volume.push([
            data[i][0], // the date
            data[i][5] // the volume
        ]);
    }

看highcharts api quickly on google，您可能需要一个事件属性，然后是load属性，以及您的逻辑，其中可能包含类似

的内容

chart: {
    events: {
        load: function () {

            // here's how you would access your series
            var series = this.series[0];
            setInterval(function () {
                //modify your series here.
            }, 1000);
        }
    }
}
