Highchart甘特图没有重叠

Question

我需要帮助才能创建一个Hichart gantt而不会重叠栏。需要将数据分组并且不要相互重叠。 EX：资源1任务A和任务B相互重叠，是否有可能将任务B放在任务A或任何其他想法之下？

Fiddle

  series: [{
    name: 'Resource 1',
    data: [{
      name: 'Task A',
      y: 0,
      start: today - (2 * day),
      end: today + (6 * day)
    }, {
      name: 'Task B',
      y: 0,
      start: today - (3 * day),
      end: today + (6 * day),
      color: 'rgba(140, 140, 140, 0.7)'
    }, {
      name: 'Task C',
      y: 0,
      start: today + (13 * day),
      end: today + (17 * day)
    }]
  }

Answer 1

很遗憾，此功能尚不支持。但是，解决方法是使用yAxis.breaks使第一类更大。然后，必须将此类别中的每个点转换为居中。检查下面发布的代码和演示。

码：

var today = new Date(),
  day = 1000 * 60 * 60 * 24;

// Set to 00:00:00:000 today
today.setUTCHours(0);
today.setUTCMinutes(0);
today.setUTCSeconds(0);
today.setUTCMilliseconds(0);
today = today.getTime();


// THE CHART
Highcharts.ganttChart('container', {
	chart: {
  	events: {
    	load: function() {
      	var chart = this,
        	series = chart.series[0];
        
        series.points.forEach(function(point) {
          point.graphic.translate(0, -25);
        });
      }
    }
  },
  title: {
    text: 'Grouping tasks vertically'
  },
  yAxis: {
    categories: ['Resource 1', 'Resource 2', 'Resource 3'],
    breaks: [{
    	breakSize: 0.5,
      from: 0,
      to: 0
    }]
  },
  plotOptions: {
    bar: {
      dataLabels: {
        enabled: true
      }
    }
  },
  series: [{
    name: 'Resource 1',
    data: [{
      name: 'Task A',
      y: 0,
      start: today - (2 * day),
      end: today + (6 * day)
    }, {
      name: 'Task B',
      y: 0.6,
      start: today - (1 * day),
      end: today + (6 * day),
      color: 'rgba(140, 140, 140, 0.7)'
    }, {
      name: 'Task C',
      y: 0,
      start: today + (13 * day),
      end: today + (17 * day)
    }]
  }, {
    name: 'Resource 2',
    data: [{
      name: 'Task D',
      y: 1,
      start: today - (1 * day),
      end: today + (6 * day)
    }, {
      name: 'Task E',
      y: 1,
      start: today + (7 * day),
      end: today + (9 * day)
    }, {
      name: 'Task F',
      y: 1,
      start: today + (11 * day),
      end: today + (12 * day)
    }, {
      name: 'Task G',
      y: 1,
      start: today + (14 * day),
      end: today + (16 * day)
    }]
  }, {
    name: 'Resource 3',
    data: [{
      name: 'Task H',
      y: 2,
      start: today - (1.5 * day),
      end: today + (4 * day)
    }, {
      name: 'Task I',
      y: 2,
      start: today + (6 * day),
      end: today + (9 * day)
    }, {
      name: 'Task J',
      y: 2,
      start: today + (10 * day),
      end: today + (14 * day)
    }, {
      name: 'Task K',
      y: 2,
      start: today + (15 * day),
      end: today + (17 * day)
    }]
  }]
});
