先看效果
1.柱状图上显示数据,使用的是series[0].label.formatter
series: [{name:'近一周每日',type: 'bar',barGap: '0',label: {normal: {show: true,formatter: '{c}%',position: "top",textStyle: {color: "#fff",fontSize: 14}}}}
2.柱形图上添加自定义icon,也是在series里面,在lable的同级添加如下代码
markPoint: {formatter: function(params){return '<img src="' + params.data.symbol.replace('image://', '')+ '"/>';},symbolSize:'15',data: [{coord: [0,10],symbolOffset:[20,-20],symbol:'image://../../../static/img/top.png'},{coord: [1,10],symbolOffset:[20,-20],symbol:'image://../../../static/img/bottom.png'},{coord: [2,20],symbolOffset:[20,-20],symbol:'image://../../../static/img/top.png'},{coord: [3,20],symbolOffset:[20,-20],symbol:'image://../../../static/img/top.png'},{coord: [4,20],symbolOffset:[20,-20],symbol:'image://../../../static/img/bottom.png'},{coord: [5,20],symbolOffset:[20,-20],symbol:'image://../../../static/img/top.png'},{coord: [6,20],symbolOffset:[20,-20],symbol:'image://../../../static/img/bottom.png'},],label:{show:true,position:'middle'}}
coord:[0,10],一个参数是我们想要添加icon柱形图的index,第二个是柱形图的value,即我们显示在柱形图上的数据
symbolOffset:使我们icon在柱状图上的位置,分别代表x,y轴的偏移量
symbol:是我们添加icon的路径,格式是image://+图片路径
