我有这个 JSON 数组。有了这些数据，使用 Highcharts 可以很好地绘制图表。
现在我正在尝试添加额外的 Y 轴（特别是对于 data1 系列）。

但是，我就是无法让额外的 Y 轴工作。这段代码有什么问题？
$(function() {
$.getJSON('testdata.php', function(data) {
// Create the chart
$('#container').highcharts('StockChart', {
title : {
text : 'test'
},
yAxis: [{
title: {
text: 'A'
}
}, {
title: {
text: 'B'
}
}, {
title: {
text: 'C'
}
}, {
title: {
text: 'D'
}
}],
series: [{
type: 'line',
name: 'A',
data: data1,
yAxis: 0,
dataGrouping: {
units: groupingUnits
}
}, {
type: 'line',
name: 'B',
data: data2,
yAxis: 1,
dataGrouping: {
units: groupingUnits
}
}, {
type: 'line',
name: 'C',
data: data3,
yAxis: 2,
dataGrouping: {
units: groupingUnits
}
}, {
type: 'line',
name: 'D',
data: data4,
yAxis: 3,
dataGrouping: {
units: groupingUnits
}
}]
});
});
});
