javascript - 如何将辅助轴添加到highstock图表？

关于javascript，我还是很耳熟。我需要一些帮助，在高库存图表中添加类似于收益的辅助轴，该辅助轴也使用$ .getJSON（JSONP）捕获json文件来填充数据。

查看JSFiddle示例here。这是播放with的示例数据集。最后，是Highcharts中secondary axis的示例。

$(function () {
    var seriesOptions = [],
        seriesCounter = 0,
        names = ['MSFT', 'AAPL', 'GOOG'],
        // create the chart when all data is loaded
        createChart = function () {

            $('#container').highcharts('StockChart', {

                rangeSelector: {
                    selected: 4
                },

                yAxis: {
                    labels: {
                        formatter: function () {
                            return (this.value > 0 ? ' + ' : '') + this.value + '%';
                        }
                    },
                    plotLines: [{
                        value: 0,
                        width: 2,
                        color: 'silver'
                    }]
                },

                yAxis: {
                floor: 0
            },

                plotOptions: {
                    series: {
                        compare: 'value'
                    }
                },

                tooltip: {
                    pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
                    valueDecimals: 2
                },

                series: seriesOptions
            });
        };

    $.each(names, function (i, name) {

        $.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=' + name.toLowerCase() + '-c.json&callback=?',    function (data) {

            seriesOptions[i] = {
                name: name,
                data: data
            };

            // As we're loading the data asynchronously, we don't know what order it will arrive. So
            // we keep a counter and create the chart when all the data is loaded.
            seriesCounter += 1;

            if (seriesCounter === names.length) {
                createChart();
            }
        });
    });
});

非常感谢您的任何帮助和解释（以便我可以学习）。我仍在尝试学习如何将jsonp和图表结合在一起，尤其是多个系列的数据和json文件。

最佳答案

像这样写：

yAxis: [{
    labels: { ... },
    title: { ... },
    ...
},
{
    labels: { ... },
    title: { ... },
    ...
}]
