我有一个样条图，我试图从今天开始在 30 天前实现通过率。基本上试图看到过去 30 天的增长。

但是，我看到 x 轴上的日期混乱了，它们要到 10 月/月加 1，这意味着 9 月 26 日有些显示为 10 月 26 日。

这是 JS 小提琴：http: //jsfiddle.net/Mn6sB/1/

这是高图表的代码 -

$(function () {
        $('#container').highcharts({
            chart: {
                renderTo: 'chartContainer',
                type: 'spline'
            },
            title: {
                text: 'Pass rate statistics'
            },
            subtitle: {
                text: 'Pass count per'
            },
            xAxis: {
                type: 'datetime',
                minTickInterval: 24 * 3600 * 1000,
                dateTimeLabelFormats: { 
                    month: '%e %b',
                    year: '%b'
                }
            },
            yAxis: {
                title: {
                    text: 'PassCount'
                },
                min: 0
            },
            tooltip: {
                formatter: function() {
                         return '<b>'+ this.series.name +
                            '</b><br/> Date: '+ Highcharts.dateFormat('%e %b',this.x)+
                                '</b><br/> Pass Count: '+ this.y;
                }
            },

使用日期时，月份从 0 开始，而不是 1。

从 js 控制台：

new Date( Date.UTC(2013,1,27) )
Tue Feb 26 2013 19:00:00 GMT-0500 (Eastern Standard Time)

new Date( Date.UTC(2013,0,27) )
Sat Jan 26 2013 19:00:00 GMT-0500 (Eastern Standard Time)
