Highcharts圖表中數據data的三種表達方式

  series:[{data:[]}]中的data有三種表達方式:javascript

  1. 數字數組
    例如data:[2,4,8],數組中的數字能夠理解爲y軸的值,圖表的x值將會自動計算(從0開始遞增,步長爲1,或者是由plotOptions中的pointStart和pointInterval指定),若是xAxis座標軸有categories,則將自動分配數組中的每一個值給每一個category。

  2. 數字數組的數組
    例如data:[[2,3],[4,1],[5,4]],兩個值的數組的數組,若是第一個值爲數字,則可理解爲x軸值,第二個值理解爲y值,若第一個值爲字符串,則其含義爲該point的name,其x值默認(從0開始遞增,步長爲1)或由plotOptions中的pointStart和pointInterval指定。

            type: 'spline',
          },
          series:[
              {
                name:'SE1',
                //data:[[100,2],[200,3],[300,4]],
                data:[['pointA',2],['pointB',3],['pointC',4]],
            }
          ]
        }
        $(function(){
          var chart1 = new Highcharts.Chart(options1);
    
        });

  3. jsonobject的數組
    例如
    data: [{
    	name: 'Point 1',
    	color: '#00FF00',
    	y: 0
    }, {
    	name: 'Point 2',
    	color: '#FF00FF',
    	y: 5
    }]能夠直接指定name等屬性
