echarts 饼图,tooltip设置show:true,悬浮效果不生效,还是没有提示气泡
我的代码:
option = {
color: color,
graphic: {
elements: [{
type: “image”,
z: 3,
style: {
image: img,
width: 140,
height: 140
},
left: ‘center’,
top: ‘center’,
},{
type: "image",
z: 3,
style: {
image: 'lx/icons/lsfx/icon.png',
width: 76,
height: 76
},
left: 'center',
top: 'center',
}],
},
tooltip: {
show: true
},
legend: {
icon: "roundRect",
orient: 'horizontal',
right: '6%',
bottom: 'center',
itemWidth: 8,
itemHeight: 42,
itemGap:30,
data:['0-50','50-100','','100-200','200-400'],
textStyle: {
color: "#fff",
fontSize: 16,
textAlign: 'center',
rich: {
hr: {
width: '6',
height: 1,
backgroundColor: '#fff',
},
a0:{
fontSize:22,
align: 'center',
color:'#00FFFF',
padding:[5,0]
},
a1:{
fontSize:22,
align: 'center',
color:'#00CFFF',
padding:[5,0]
},
a2:{
fontSize:22,
align: 'center',
color:'#006CED',
padding:[5,0]
},
a3:{
fontSize:22,
align: 'center',
color:'#FFE000',
padding:[5,0]
},
b:{
fontSize:16,
align: 'center',
padding:[5,0]
}
},
},
formatter: function(params) {
for (var i = 0; i < trafficWay.length; i++) {
if (trafficWay[i].name === params) {
var percent = ((trafficWay[i].value / total) * 100).toFixed(0);
return ' {a'+ i +'|'+percent + '%}\n{hr| }\n{b|' + params+'}'
}
}
}
},
toolbox: {
show: false
},
series: seriesOption
}
尝试了以下几种方法:
1、{
trigger: ‘axis’,
axisPointer: {
type: ‘shadow’,
},
textStyle: {
color: ‘#fff’,
fontSize: 14,
}
}
2、tooltip: {
show: true,
trigger: “item”
},
3、在echarts社区图源设置
tooltip: {
show: true
},
社区上能生效,我本地代码还是不生效
最终找到原因:图例影响了它
最终解决办法:
tooltip: {
show: true,
trigger: “item”
},
并且在echarts图所在div 设置样式如下:
最终效果如下:
多亏了我同事前端小姐姐,默默的给她比个心❤
