Highcharts 24小時制

Question

我有一張圖表顯示了根據發佈時間標籤的流程。我希望X軸從00:00開始以小時顯示時間，並在1小時之間顯示24小時至23:00的整個週期。這是問題，它只顯示00：00-22：00，我不能理解爲什麼。這裏是代碼：

var Chart = (function() { 
    function Chart() { 
     var _this = this; 
     this.data = { "TW": [174, 5, 278, 269, 282, 283, 271, 316, 251, 265, 273, 261, 265, 265, 45, 45, 60, 60, 46, 370, 428, 465, 404, 372], "IG": [266, 217, 221, 240, 220, 206, 193, 219, 186, 233, 213, 213, 243, 243, 109, 115, 128, 136, 196, 360, 483, 432, 382, 303], "GP": [31, 14, 13, 17, 14, 11, 8, 13, 12, 11, 20, 45, 22, 29, 17, 19, 27, 21, 18, 24, 37, 35, 20, 21], "total": 12009, "toptags": [{ "tag": "#paradisehotelSE", "count": 3600 }, { "tag": "#TV4", "count": 3240 }, { "tag": "#IdolSE", "count": 3126 }] }; 
     this.load(function() { 
      _this.googleplus = _this.getData('googleplus'); 
      _this.twitter = _this.getData('twitter'); 
      _this.instagram = _this.getData('instagram'); 

      _this.init(); 
     }); 

Chart.prototype.init = function() { 
     var hour = 3600 * 1000; 

     $('#graph').highcharts({

這是所有與圖表相關的Javascript，非常感謝您的關注。

Answer 1

您的圖確實顯示22:00至23:00的數據。不過，問題在於23點報時被壓制。

爲什麼？問題一，你已告訴高分榜startOnTick，但你還沒有啓用相應的endOnTickoption。問題二，你的maxPadding選項。通過將其設置爲0並且數據在23:00結束，您已給Highcharts沒有空間添加最後一個刻度標籤。

//maxPadding: 0, 
endOnTick: true 

這是fiddle。
