Highcharts vbp无法读取未定义的属性长度

Question

我正在尝试实现与此非常相似的内容：

https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/stock/demo/sma-volume-by-price

我就像这样设置我的数据，

for (i; i < dataLength; i += 1) {
    ohlc.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
    ]);
}

this.chartOptions.series[0]['data'] = ohlc;
this.chartOptions.series[1]['data'] = volume;

但是我遇到了这个错误：
