如何为图表中显示的vis.js时间轴制作所有内容

Question

我正在使用vis.js时间线图表和右侧显示的所有项目内容。但是当某些内容包含大量文本时，并非所有内容都显示在图表上。我想知道 （1）如果无论如何都要计算内容长度并重置图表的宽度。 （2）如果可以让最后一组项目内容左对齐

感谢您的任何建议

问题是右侧的某些内容未显示在图表上 documentation

这是代码

 var items = new vis.DataSet([
    {id: 1, className:'item4', content: 'item 1', start: '2016-04-10'},
    {id: 2, className:'item5', content: 'item 2', start: '2016-04-10'},
    {id: 3, className:'item4', content: 'item 3', start: '2016-04-10'},
    {id: 5, className:'item4', content: 'item 5', start: '2016-04-18'},
    {id: 6, className:'item5', content: 'item 6', start: '2016-04-18'},
    {id: 7, className:'item4', content: 'item 7', start: '2016-04-18'},
    {id: 8, className:'item5', content: 'item 8', start: '2016-04-18'},
    {id: 9, className:'item4', content: 'This item has long title', start: '2016-04-25'},
    {id: 10, className:'item5', content: 'item 10', start: '2016-04-25'},
    {id: 11, className:'item6', content: 'item 11', start: '2016-04-25'}
  ]);

    var options = {
     showCurrentTime: false,
     align: 'left',
     moveable: false,
     orientation: {axis: 'both', item: 'top'}, 
     height: 400,
     margin: {
         axis: 100
    }
  };
  var timeline = new vis.Timeline(container, items, options);
