{
    ActusLibrary.GoogleChartReportFilters obj = new ActusLibrary.GoogleChartReportFilters();
    List<object> lstData = ActusLibrary.Objectives.GetChartData(obj,ApConfig.CurrentCompany.CompId);
    return lstData;
}

    string query = "usp_GetObjectivesDetailsForGoogleChart";
    string constr = ApConfig.ConString;
    List<object> chartData = new List<object>();
    chartData.Add(new object[]
    {
        "Objective_Status", "Percentage"
    });
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand(query))
        {
            cmd.CommandType = CommandType.StoredProcedure;

            cmd.Parameters.AddWithValue("@CompanyId", companyId);
            cmd.Parameters.AddWithValue("@DateFilter", objFilter.DateFilter);
            cmd.Parameters.AddWithValue("@MoreThanLessThanStatus", objFilter.MoreThanLessThanStatus);
            cmd.Parameters.AddWithValue("@MoreThanLessThanValue", objFilter.MoreThanLessThanValue);
            cmd.Parameters.AddWithValue("@ObjectivesStatus", objFilter.ObjectivesStatus);
            cmd.Parameters.AddWithValue("@ObjectivePeriod", objFilter.ObjectivePeriod);

            cmd.Connection = con;
            con.Open();
            using (SqlDataReader sdr = cmd.ExecuteReader())
            {
                while (sdr.Read())
                {
                    chartData.Add(new object[]
                    {
                        sdr["Objective_Status"].ToString(), sdr["Percentage"]
                    });
                }
            }
            con.Close();
            return chartData;
        }
    }

web methods can't access user controls. If your webmethod needs data from the page then it needs to accept that data via method parameters and your calling js needs to read the data from the page and pass it as parameters when it called the method. If you google calling a webmethod with parameters from javascript you'll find examples of this. Needless to say the reverse is also true, your webmethod can't update controls on the page either, the webmethod will need to return the data (serialised as json) and the calling js will need to update the DOM to reflect the data passed back from the webmethod...ie adding\removing markers etc.

XML

filterRecords = [];

        filterRecords[0] = $("#<%=drpDateFilter.ClientID%>").val();
        filterRecords[1] = $("#<%=drpMoreThanLessThanStatus.ClientID%>").val();
        filterRecords[2] = $("#<%=drpMoreThanLessThanValue.ClientID%>").val();
        filterRecords[3] = $("#<%=drpObjectivesStatus.ClientID%>").val();
        filterRecords[4] = $("#<%=drpObjectivePeriod.ClientID%>").val();


        $.ajax({
            type: "POST",
            url: "Home.aspx/GetChartData",
            data: JSON.stringify({ paramName: filterRecords }),

and on Webmethod :-

XML

[WebMethod]
      public static List<object> GetChartData(string[] paramName)
      {

}

F-ES Sitecore is correct. WebMethod should get some parameter and return you some value. Take that value and do any operation you want through JavaScript/jQuery.
