自定义换行,内容很长的时候
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'
},
textStyle:{
align:'left'
},
formatter:function (params) {
var newParamsName ='';
var title = '';
var titleLength = params[0].name.length;
var rowCount = 20;
var rowNumber = Math.ceil(titleLength / rowCount);
if(titleLength>rowCount){
for (var i = 0; i < rowNumber; i++) {
var tempStr = "";
var start = i * rowCount;
var end = start + rowCount;
if (i == rowNumber - 1) {
tempStr = params[0].name.substring(start, titleLength);
} else {
tempStr = params[0].name.substring(start, end) + "</br>";
}
newParamsName += tempStr;
}
}else {
newParamsName = params[0].name;
}
//返回小圆圈和后面的数量
return (newParamsName+"</br>"
+"<span style='display:inline-block;margin-right:5px;border-radius:10px;width:9px;height:9px;background-color:"+params[0]['color']+"'></span>"+
"汇总:"+params[0]['value']); },
效果:
