VS ASP.NET

Steps to use in ASP.NET

Step1 : Add javascript libraries on head section

Step2: Now make json function

<script type="text/javascript" language="javascript">
     google.load('visualization', '1', {'packages': ['columnchart']});
    function PageViews(response)
    {
        if(response == null)
        {
            var days = 10;
            var request = "{'NoOfDays':"+ days +"}";
            GetData("Default.aspx/GetDailyVisits",request,PageViews);
        }
        else
        {
            var data = new google.visualization.DataTable();
            data.addColumn('string', 'Date');
            data.addColumn('number', 'Page Views');
            data.addRows(response.d.length);
            for (var i = 0; i < response.d.length; i++) {
                data.setValue(i, 0, response.d[i].Date);
                data.setValue(i, 1, response.d[i].Visits);
            }
            var container = document.getElementById('spnChart');
            container.innerHTML = "";
            var chart = new google.visualization.ColumnChart(container);
            chart.draw(data, {width: 800, height: 300, is3D: true, title: 'Page Views', legend:'none', titleX:'Date', titleY:'Page Views'});
        }
    }
    function GetData(func,arg,SFunc) {
        $.ajax({
            type: "POST",
            url: func,
            data: arg,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: SFunc
        });
    }
</script>

Step3: Now in code behind, make static webmethod function to return list

[WebMethod]
    public static List<DateNVisits> GetDailyVisits(int NoOfDays)
    {
        List<DateNVisits> ts = new List<DateNVisits>();
        for (int i = 0; i < NoOfDays; i++)
        {
            ts.Add(new DateNVisits(DateTime.Now.AddDays(i).ToShortDateString(),i));
        }
        return ts;
    }
public class DateNVisits
{
    public DateNVisits()
    {
    }
    public DateNVisits(string d, int v)
    {
        Date = d;
        Visits = v;
    }
    public string Date
    {
        get;
        set;
    }
    public int Visits
    {
        get;
        set;
    }
}

Thats all
