Ajax is a web development technique that creates interactive Web applications. The following small series for you to share an AJAX dynamic assignment Echarts example (pie chart and column chart), has a very good reference value, I hope to be helpful to everyone. Let's take a look at it with a little knitting.

This paper is an example of dynamic assignment of Ajax in column and pie charts.

First, pie chart assignment steps

(1) JSP page

<!--introduced Echarts------<script src= "Js/echarts.js" ></script> <body> <!--to Echarts Prepare a DOM pie chart with size (wide height)---<p id= "first" style= "width:600px;height:400px;" ></p> [HTML] View plain copy</body>

(2) JS page

Pie chart template var dom = document.getElementById ("First"), var mychart = Echarts.init (DOM), var app = {};option = Null;option = { Title: {text: ' User location record ', Subtext: ', x: ' Center '}, tooltip: {trigger: ' item ', formatter : "{A} <br/>{b}: {C} ({d}%)"}, Legend: {Orient: ' Vertical ', x: ' Left ', data:[]}, to        Olbox: {show:true, feature: {mark: {show:true}, DataView: {show:true, readonly:false},              Magictype: {show:true, type: [' pie ', ' funnel '], option: {funnel: {          x: ' 25% ', Width: ' 50% ', funnelalign: ' Left ', max:1548}  }}, restore: {show:true}, Saveasimage: {show:true}}}, Calculable:true, series     : [{name: ', type: ' Pie ', radius: ' 55% ', center: [' 50% ', ' 60% '], data:[]} ]  };; if (option && typeof option = = = "Object") {mychart.setoption (option, true);}  Pie chart Dynamic Assignment var year = $ ("#year-search"). Val ();  var mouth = $ ("#mouth-search"). Val (); $.ajax ({type: "Get", url:rootpath+ "/wxbound/getpiedatabymouth.action", Data: {"Year": Year, "Mouth": mouth}         , Cache:false,//Disable cache DataType: "JSON", success:function (Result) {var names=[];//define two arrays         var nums=[]; $.each (Result,function (key,values) {///Here I am returning list<string,map<string,string>> loop map Names.push (values.           Province_name);           var obj = new Object ();           Obj.name = Values.province_name;           Obj.value = Values.count;          Nums.push (obj);        });                Mychart.setoption ({//Load data graph legend: {Data:names}, series: {      According to the name corresponding to the corresponding series name: [' Quantity '], data:nums}}); }, Error:function (XMLHttpRequest, textsTatus, Errorthrown) {alert ("Query failed"); }    });

(3) Background code according to your own code is good

(4) Display style

Second, column chart assignment step

(1) JSP page

<!--introduced Echarts------<script src= "Js/echarts.js" ></script> <body> <!--to Echarts Prepare a DOM column with size (wide height)---<p id= "second" style= "width:600px;height:400px;" ></p> </body>

(2) JS page

Column chart template var domlong = document.getElementById ("second"); var Mychartsecond = Echarts.init (Domlong); var app = {};option = Nu Ll;option = {color: [' #3398DB '], tooltip: {trigger: ' axis ', Axispointer: {//Axis indicator, axis trigger valid Ty PE: ' Shadow '//default to line, Optional: ' Lines ' |     ' Shadow '}, Grid: {left: ' 3% ', right: ' 4% ', bottom: ' 3% ', containlabel:true}, Xaxis: [  {type: ' Category ', data: [], Axistick: {alignwithlabel:true}}], YAxis:       [{type: ' value '}], series: [{name: ' Direct Access ', type: ' Bar ', BarWidth: ' 60% ', Data:[]}]};if (option && typeof option = = = "Object") {mychartsecond.setoption (option, true);} Assign the column chart var year = $ ("#year-search"). Val (); $.ajax ({type: "POST", url:rootpath+ "/wxbound/getwxboundlist.action", Data: {"Year": Year}, Cache:f  Alse,//Disable cache DataType: "JSON", success:function (Result) {   Console.log (result);   var linnames=[];     var linnums=[];     $.each (Result.lin,function (key,values) {Linnames.push (Values.mouth);    Linnums.push (Values.count);   });  Column Chart Assignment mychartsecond.setoption ({//Load data graph Xaxis: {data:linnames}, Series:        {//According to the name corresponding to the corresponding series name: [' Quantity '], data:linnums}});      }, Error:function (XMLHttpRequest, Textstatus, Errorthrown) {alert ("Query failed"); }    });}

(3) Backstage code part according to own need is good ...
