当涉及到javascript时,我的耳朵仍然很潮湿。我需要一些帮助来添加一个辅助轴,这个收入类似于一个highstock图表,它也使用$ .getJSON(JSONP)来阻止json文件填充数据。
查看JSFiddle示例here。以下是要播放with的示例数据集。最后,在Highcharts中的secondary axis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();
}
});
});
});
非常感谢任何帮助和解释(所以我可以学习)。我还在尝试学习如何将jsonp和图表绑定在一起,尤其是多个数据系列和json文件。

像这样写:
yAxis: [{
labels: { ... },
title: { ... },
...
},
{
labels: { ... },
title: { ... },
...
}]
