利用echart 做以特定数值为分界线的图表 原

利用echart 做以特定数值为分界线的图表，下面的例子以1为分界线的例子      <script>    var axisData = ["8","9","10","11","12","13","14","15","16","17","18"];      var yxisData = [0.26, 1.01, 1.17, 1.17, 0.77, 0.90, 3.03, 0.99, 1.19, 4.83, 1.57];      var yxisData0=[];      var yxisData1=[];      var interval;      var maxy = Math.max.apply(null,yxisData);      if(maxy <= 2){        interval=0.1;      }else{        interval=0.2;      }   $.each(yxisData,function(index,item){   if(item >=1)   {    item -=1;    yxisData1.push(item);    yxisData0.push(1);   }   else   {    yxisData1.push(1-item);    yxisData0.push(item);   }   })  option1 = {       title : {                  text : '公司名称',              },      legend: {                  data:['不均匀系数'],                 },      tooltip : {         trigger: 'axis',         axisPointer : {            // 坐标轴指示器，坐标轴触发有效             type : 'shadow'        // 默认为直线，可选为：'line' | 'shadow'         },         formatter: function (params) {             var tar;             tar = params[1];             return tar.name + '<br/>' + tar.seriesName + ' : ' + (yxisData[tar.dataIndex]);         }     },  grid: {},     xAxis : [         {             type : 'category',             data : axisData         }     ],    yAxis: {interval:interval, },// y轴不能删除      series: [         {             name: '辅助',             type: 'bar',             stack: '总量',             itemStyle: {                 normal: {                     barBorderColor: 'rgba(0,0,0,0)',                     color: 'rgba(0,0,0,0)'                 },                 emphasis: {                     barBorderColor: 'rgba(0,0,0,0)',                     color: 'rgba(0,0,0,0)'                 }             },    data:yxisData0         },         {             name: '不均匀系数',             type: 'bar',             stack: '总量',             data: yxisData1         },   ] };    var myChart1 = echarts.init(document.getElementById('barchart1'),theme);   myChart1.setOption(option1);   ObjectResize(myChart1.resize)   function ObjectResize(fn){   if(window.addEventListener)  {  window.addEventListener("resize",fn,false);    }   else   {  window.attachEvent("onresize",fn)   }   }  </script>
