我正在使用以下方法动态填充 highcharts 中的类别，但它对我不起作用
var weeklyIndicators;
var cats = '';
$.when(
$.getJSON('weeklyindicators', function(data) {
weeklyIndicators = data;
})
).then(function() {
$.each(weeklyIndicators, function(i, item) {
if (cats.indexOf(item.indicatorTimestamp) == -1){
cats += "'" + item.indicatorTimestamp + "'" + ',';
}
});
cats = cats.substring(0, cats.length - 1);
console.log(cats);
// here is the output: '2016-01-30','2016-01-31','2016-02-01','2016-02-02','2016-02-03','2016-02-04','2016-02-05'
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Monthly Average Rainfall'
},
subtitle: {
text: 'Source: WorldClimate.com'
},
xAxis: {
categories: [cats],
crosshair: true
},
yAxis: {
min: 0,
title: {
text: 'Rainfall (mm)'
}
},
tooltip: {
headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
'<td style="padding:0"><b>{point.y:.1f} mm</b></td></tr>',
footerFormat: '</table>',
shared: true,
useHTML: true
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: 'Tokyo',
data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6]
}, {
name: 'New York',
data: [83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0]
}, {
name: 'London',
data: [48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0]
}, {
name: 'Berlin',
data: [42.4, 33.2, 34.5, 39.7, 52.6, 75.5, 57.4]
}]
});
});
如果我复制/粘贴 console.log 的输出，它工作正常，有什么帮助吗？

此外，我需要该系列充满活力，任何帮助将不胜感激。
最佳答案
用这个
var cats =[]
$.each(weeklyIndicators, function(i, item) {
if (cats.indexOf(item.indicatorTimestamp) == -1){
cats.push(item.indicatorTimestamp);
}
});
并直接在您的类别中使用此cats数组
categories = cats //not in []
