Step-5: Add a webpage and design for show Google column chart with database data.

            <div id="chart_div" style="width:500px;height:400px">
                <%-- Here Chart Will Load --%>

Step-6: Add Jquery code for call server side function for get data from sql server database.

Write this below jquery code inside page <head></head> section.
Jquery Code
           <%-- Here We need to write some js code for load google chart with database data --%>
            <script src="Scripts/jquery-1.7.1.js"></script>
            <script type="text/javascript" src="https://www.google.com/jsapi"></script>

                var chartData; // globar variable for hold chart data
                google.load("visualization", "1", { packages: ["corechart"] });

                // Here We will fill chartData

                $(document).ready(function () {
                        url: "GoogleChart.aspx/GetChartData",
                        data: "",
                        dataType: "json",
                        type: "POST",
                        contentType: "application/json; chartset=utf-8",
                        success: function (data) {
                            chartData = data.d;
                        error: function () {
                            alert("Error loading data! Please try again.");
                    }).done(function () {
                        // after complete loading data

                function drawChart() {
                    var data = google.visualization.arrayToDataTable(chartData);

                    var options = {
                        title: "Company Revenue",
                        pointSize: 5

                    var columnChart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
                    columnChart.draw(data, options);



Step-7: Write server side code (function) for get data from sql server database.

Before writing code add this namespace to your code behind page.

            using System.Web.Script.Services;
           using System.Web.Services;
Here is the function, which is called by jquery code.
            [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
            public static object[] GetChartData()
                List<GoogleChartData> data = new List<GoogleChartData>();
                //Here MyDatabaseEntities  is our dbContext
                using (MyDatabaseEntities dc = new MyDatabaseEntities())
                    data = dc.GoogleChartDatas.ToList();

                var chartData = new object[data.Count + 1];
            chartData[0] = new object[]{
                "Books & Media",
                "Home & Kitchen"

            int j = 0;
            foreach (var i in data)
                chartData[j] = new object[] {i.Year.ToString(), i.Electronics, i.BookAndMedia, i.HomeAndKitchen };
            return chartData;
