JSON Question

Why Google Chart does not work ASP MVC app?

I have method on my controller, who return Json

public JsonResult CompanyChart()

var data = db.adusers;
var selectUsers = from s in data where (s.Company != null) select s;
int fenixPlus = (from fP in data where (fP.Company == "ООО \"Феникс+\"") select fP).Count();
int fenixPresent = (from fP in data where (fP.Company == "ООО \"Феникс-Презент\"") select fP).Count();

var dataObj = new object[]
new object[] {"Компания","Количество"},
new object[] { "ООО \"Феникс+\"", fenixPlus},
new object[] { "ООО \"Феникс-Презент\"", fenixPresent}

return Json(dataObj, JsonRequestBehavior.AllowGet);

Json looks like this
[["Компания","Количество"],["ООО \"Феникс+\"",53],["ООО \"Феникс-Презент\"",42]]

In my view side I have a jquery post request

url: '@Url.Action("CompanyChart", "Users")',
type: 'post',
dataType: "json",
success: function (data) {

Then, I try draw google pie chart

google.charts.load("current", { packages: ["corechart"] });
function drawChart(data) {

var array = JSON.parse(data);
var dataV = new google.visualization.DataTable(array);
var options = {
title: 'My Daily Activities',
pieHole: 0.4,

var chart = new google.visualization.PieChart(document.getElementById('donutchart'));
chart.draw(dataV, options);

Not work, error in console
Uncaught SyntaxError: Unexpected token К in JSON at position 0

I don't understand, why my code does not work?


JsonResult returns to the caller a JSON object not a string of JSON content, therefore, you don't need to call JSON.parse.

Simply change

var array = JSON.parse(data);


var array = data;
