• Highcharts图表中数据data的三种表达方式


      series:[{data:[]}]中的data有三种表达方式:

    1. 数字数组
      例如data:[2,4,8],数组中的数字可以理解为y轴的值,图表的x值将会自动计算(从0开始递增,步长为1,或者是由plotOptions中的pointStart和pointInterval指定),如果xAxis坐标轴有categories,则将自动分配数组中的每个值给每个category。

    2. 数字数组的数组
      例如data:[[2,3],[4,1],[5,4]],两个值的数组的数组,如果第一个值为数字,则可理解为x轴值,第二个值理解为y值,若第一个值为字符串,则其含义为该point的name,其x值默认(从0开始递增,步长为1)或由plotOptions中的pointStart和pointInterval指定。

              }
            ]
          }
          $(function(){

          });

        <div id="container1" style="min-800px;height:400px;"></div>
      </body>
      </html>

    3. jsonobject的数组
      例如
      data: [{
      	name: 'Point 1',
      	color: '#00FF00',
      	y: 0
      }, {
      	name: 'Point 2',
      	color: '#FF00FF',
      	y: 5
      }]
      可以直接指定name等属性
