日期標籤不顯示爲每列

Question

我有我已經工作了一下昨天的圖表，並在今天上午的jsfiddle：

http://jsfiddle.net/XJES3/6/

如果你看看你會看到列的xAxis標籤並不總是顯示出來。我確定有一個設置強迫他們總是顯示或可能設置間隔的方式，但我目前在API文檔中找不到它。如果有人能指出我正確的方向，會很樂意。

非常感謝。下面

Highcharts代碼：

var go_local_scriblio_authority_history = new Highcharts.Chart({ 
    chart: { 
     renderTo: 'go-local-scriblio-authority-history',

      formatter: function() { 
       return Highcharts.dateFormat('%b', this.value).toUpperCase(); 
      }

});

您需要設置tickInterval： http://api.highcharts.com/highcharts#xAxis.tickInterval

http://jsfiddle.net/XJES3/7/

tickInterval:86400*30 * 1000, //30 days, in miliseconds
