  public class tempcountry     {         public string country { get; set; }         public int visits { get; set; }      }      [httpget]     public iactionresult charts_json()     {         list<tempcountry> tempcountry = new list<chartcontroller.tempcountry>();          tempcountry tobj = new tempcountry();         tobj.country = "pakistan";         tobj.visits = 500;          tempcountry.add(tobj);          tobj = new tempcountry();         tobj.country = "japan";         tobj.visits = 1000;          tempcountry.add(tobj);          tobj = new tempcountry();         tobj.country = "india";         tobj.visits = 3000;          tempcountry.add(tobj);          tobj = new tempcountry();         tobj.country = "austrailia";         tobj.visits = 4000;          tempcountry.add(tobj);          return json(tempcountry);       }

the following angularjs controller.

var myapp = angular.module("main", []);

myapp.controller("mycontroller", function ($scope,$http) {

$http({     method: "get",     url: "/chart/charts_json" }).then(function mysuccess(response) {       chartdata = response.data;     var chart = new amcharts.amserialchart();     chart.dataprovider = response.data;     chart.categoryfeild = "country";     var graph = new amcharts.amgraph();     graph.valuefield = "visits";     chart.addgraph(graph);     chart.write('chartdiv'); });

});

the following view code (mvc asp.net core).

@section scripts {     <script src="~/js/amcharts/amcharts.js"></script>     <script src="~/js/amcharts/serial.js"></script>     <script src="~/lib/angular/angular.js"></script>     <script src="~/js/mainapp.js"></script> } <p>this chart view page</p> <body>     <div ng-app="main">         <div ng-controller="mycontroller">         </div>     </div>     <div id="chartdiv" style="width:640px; height: 480px;">     </div> </body>

the following screenshot of output getting enter image description here

chart.categoryfeild = "country";

categoryfeild not valid amcharts property.

if literally how spelling property, can edit column chart on amcharts website , reproduce same undefined column names generating using categoryfeild.

instead, please try replacing categoryfeild categoryfield.
