Answer 1

echarts.js根后台数据动态更新数据显示：
function initDefaultChart(ec){
echarts = ec;

var list_devData = ${pointDataMassage};
/* console.info(list_devData); */
var str = "";
for (var one in list_devData){
/* console.info("one",list_devData[one]); */
var id_data =list_devData[one].dataId;
var data_unit = list_devData[one].dataUnit;
var dataSort = list_devData[one].dataSort;
/* console.info("id",id_data); */

if(document.getElementById("attr_"+id_data)!=undefined){/* !exp && typeof(exp)!="undefined" && exp!=0 */

var myChart = ec.init(document.getElementById("attr_"+id_data));
var option = {
tooltip : {
formatter: "{b} <br/>{c}{a}"
},
toolbox: {
show : false,
feature : {
mark : {show: true},
restore : {show: true},
saveAsImage : {show: true}
}
}

}
