我不确定发生了什么，但日期显示在轴上，并在一个月后的工具提示中显示。因此，此图表上数据的第一个日期是 7 月，但它显示为 8 月，依此类推。有任何想法吗？我已将代码放入 JSFiddle ( http://jsfiddle.net/Z2VGL/1/ ) 以及以下：
$(function () {
$('#container').highcharts({
chart: {
type: 'spline'
},
title: {
text: ''
},
plotOptions: {
series: {
lineWidth: 5,
marker: {
fillColor: '#FFFFFF',
lineWidth: 2,
radius: 6,
lineColor: null // inherit from series
}
}
},
subtitle: {
text: ''
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: { // don't display the dummy year
month: '%e %b',
year: '%b'
}
},
yAxis: {
title: {
text: 'Ability Score (out of 100)',
style: {
color: '#323A45',
fontWeight: 'bold'
}
},
min: 0
},
tooltip: {
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' + Highcharts.dateFormat('%e %b', this.x) + ': ' + this.y;
}
},
series: [{
name: 'Overall Ability',
// Define the data points. All series have a dummy year
// of 1970/71 in order to be compared on the same x axis. Note
// that in JavaScript, months start at 0 for January, 1 for February etc.

提前致谢。
