           trigger: 'axis',
           axisPointer: {
               type: 'shadow'
           }
       },
       legend: {
           data: ['Forest', 'Steppe', 'Desert', 'Wetland']
       },
       toolbox: {
           show: true,
           orient: 'vertical',
           left: 'right',
           top: 'center',
           feature: {
               mark: {show: true},
               dataView: {show: true, readOnly: false},
               magicType: {show: true, type: ['line', 'bar', 'stack', 'tiled']},
               restore: {show: true},
               saveAsImage: {show: true}
           }
       },
       xAxis: [
           {
               type: 'category',
               axisTick: {show: false},
               data: ['2012', '2013', '2014', '2015', '2016']
           }
       ],
       yAxis: [
           {
               type: 'value'
           }
       ],
       series: [
           {
               name: 'Forest',
               type: 'bar',
               barGap: 0,
               data: [320, 332, 301, 334, 390],
               itemStyle:{
                   color:(params)=>{
                       return 'white'
                   }
               }
           },
           {
               name: 'Steppe',
               type: 'bar',
               data: [220, 182, 191, 234, 290],
               itemStyle:{
                   color:(params)=>{
                       return '#79D4F0'
                   }
               }
           },
           {
               name: 'Desert',
               type: 'bar',
               data: [150, 232, 201, 154, 190],
               itemStyle:{
                   color:(params)=>{
                       return 'rgba(205,229,170,1)'
                   }
               }
           },
           {
               name: 'Wetland',
               type: 'bar',
               data: [98, 77, 101, 99, 40],
               itemStyle:{
                   color:'#00FF00'
               }
           }
       ]
   };
   
   ### What is expected?
   series->itemStyle->color(params)=>{} callback function 影响图例标记的颜色
   
   ### What is actually happening?
   itemStyle->color的回调函数不影响图例标记颜色
