请教如何样让ECharts从后台获取数据并展示？

调用后台接口，ajax获取数据 function getspslztslbh(city,date){ $.ajax({ url: ctx+"/index/spscztGroup.do ", type:"post", data: { "city": city, "date":date }, dataType: "json", success: function(data){ 拿到数据重新setoption myChartz.setOption({ xAxis: { data: data.list2 }, yAxis: [{ min: mind, max: maxd, interval: ava1 },{ min: mind3, max: maxd3, interval: ava2 }], }
