如何处理Highcharts X轴数据过多时显示问题

Answer 1

方法一：在Axis（包括xAxis和yAxis）有一个属性tickInterval，number类型，表示间隔，也就是间隔多少个值显示，比如设置为5，则表示每隔5个值才显示一个，在上面的基础上，经过设置tickInterval值为5，效果如下:

xAxis: {
                tickInterval: 5,
                categories:['2013-08-01 00:00:00','2013-08-01 00:00:10','2013-08-01 00:00:20','2013-08-01 00:00:30','2013-08-01 00:00:40','2013-08-01 00:00:50','2013-08-01 00:01:00','2013-08-01 00:01:10','2013-08-01 00:01:20','2013-08-01 00:01:30','2013-08-01 00:01:40','2013-08-01 00:01:50','2013-08-01 00:02:00','2013-08-01 00:02:10','2013-08-01 00:02:20','2013-08-01 00:02:30','2013-08-01 00:02:40','2013-08-01 00:02:50','2013-08-01 00:03:00','2013-08-01 00:03:10','2013-08-01 00:03:20','2013-08-01 00:03:30','2013-08-01 00:03:40','2013-08-01 00:03:50','2013-08-01 00:04:00'],
                labels:{
                    x:45,//调节x偏移
                    //y:-35,//调节y偏移
                    //rotation:25//调节倾斜角度偏移
                 }
              },

方法二：设置滚动条

  //设置滚动条   
   scrollbar: {
       enabled: true
   },
   series: [{
       data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4,194.1, 95.6, 54.4,29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4,194.1, 95.6, 54.4,29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4,194.1, 95.6, 54.4,29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4,194.1, 95.6, 54.4]
