Try like this

Javascript

Get the data from controller using ajax
jQuery ajax() Method[^]
jQuery.ajax() | jQuery API Documentation[^]

HTML

<script>
    $(document).ready(function () {

        var link = '@Url.Action("GetData", "Home")';

        $.ajax({
            type: "POST",
            url: link,
            //data: args,
            dataType: "json",
            success: function (data) {
                genChart(data);
            }
        }); 
    });

    function genChart(data) {
        var m1 = new Morris.Line({
            element: 'line-chart',
            data: data,
            xkey: 'y',
            ykeys: ['a', 'b'],
            labels: ['Series A', 'Series B'],
            lineColors: ['#D9534F', '#428BCA'],
            lineWidth: '2px',
            hideHover: true
        });
    }
</script>

Controller
Get the data from a List and convert it to JSON format and return it to the Ajax method

C#

public ActionResult GetData()
        {
            var data = new[] {
                new { y = "2006", a = 30, b = 20 },
                new { y = "2007", a = 75, b = 65 },
                new { y = "2008", a = 50, b = 40 },
                new { y = "2009", a = 75, b = 60 },
                new { y = "2010", a = 50, b = 80 },
                new { y = "2011", a = 30, b = 50 }
            };  // This is  hardcoded data, you can get the data from a List 
            return Json(data);
            
        }

Let me know if you face any issue.

Thanks for your time Karthik, i am able to get results from your code, but i am trying this way and not able to display results please have a look

Model
<pre>
public class GraphModel
{
public string label { get; set; }
public string value { get; set; }
public string year { get; set; }
}
</pre>
Controller
<pre>
public ActionResult GraphData()
{
GraphModel oGraphModel = null;
List<graphmodel> lstGraphModel = new List<graphmodel>();
int index = 0;
Random random = new Random();
while (index < 5)
{
oGraphModel = new GraphModel();
oGraphModel.label = DateTime.Now.AddDays(index).ToString("dd-MM-yyyy");
oGraphModel.value = random.Next(index, 5000).ToString();
oGraphModel.year = (index + 2000).ToString();
lstGraphModel.Add(oGraphModel);
index++;
}
var jsonSerializer = new JavaScriptSerializer();
string data = jsonSerializer.Serialize(lstGraphModel);
return Json(data, JsonRequestBehavior.AllowGet);
}
</pre>
VIEW
<pre>
<script>
$(document).ready(function () {
var link = '@Url.Action("GraphData", "Home")';
$.ajax({
type: "POST",
url: link,
//data: args,
dataType: "json",
success: function (data) {
genChart(data);
}
});
});

function genChart(data) {
var m1 = new Morris.Line({
element: 'line-chart',
data: data,
xkey: 'year',
ykeys: ['value'],
labels: ['value'],
lineColors: ['#D9534F'],
lineWidth: '2px',
hideHover: true
});
}
</script>
</pre>

use this code in the controller

public ActionResult GraphData()
{
GraphModel oGraphModel = null;
List < graphmodel > lstGraphModel = new List < graphmodel > ();
int index = 0;
Random random = new Random();
while (index < 5)
{
oGraphModel = new GraphModel();
oGraphModel.label = DateTime.Now.AddDays(index).ToString("dd-MM-yyyy");
oGraphModel.value = random.Next(index, 5000).ToString();
oGraphModel.year = (index + 2000).ToString();
lstGraphModel.Add(oGraphModel);
index++;
}

return Json(lstGraphModel);
}

let me know if the above code works fine

MayankSemwal 11-Mar-16 3:29am

Marked, Thanks again

:)

MayankSemwal 11-Mar-16 3:30am

So, i was serializing data That was the reason Code was not working?

Karthik_Mahalingam 11-Mar-16 3:33am

hmm
always use like this.

var jsonresult = Json(data);
jsonresult.MaxJsonLength = int.MaxValue;
jsonresult.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
return jsonresult;
