我希望x軸的時間間隔爲半個月。我想通了，我可以用pointInterval，但我不知道爲什麼它如預期highcart.js pointInterval 15天datetime x軸

如果你需要半個motnh（15天），爲什麼你設置13？ – 2014-11-07 10:50:01

設置你想要的是tickInterval ，而不是點間隔。您還需要指定startOnTick：true以使其從第一個點開始。

xAxis: { 
     type: 'datetime', 
     tickInterval: 13 * 24 * 3600 * 1000, //half month interval 
     pointStart: Date.UTC(2014, 7, 26), 
     startOnTick: true, 
     dateTimeLabelFormats: { 
      month: '%b %e', 
      year: '%b' 
     } 
    },
