I want to replace the hard coded data in the code below with data from my database that I've created using the Code First approach.

However, I literally have no idea how because I'm still pretty new to this. The Google Chart works perfectly with the hard coded values, but how to approach it using actual data from my database is where my understanding ends. There are plenty of tutorials out (on Code First) on how to do this **using hard coded** data but none on **using data from the database**. 

Can someone please provide me with a detailed approach on how to do this so that I can understand it better? I'll greatly appreciate it and thanks in advance!

If there is any additional information required please let me know and I will try to add it in to the question. 

**Model:**

```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace HealthHabitat.Models
{
    public class ProductModel
    {
        public string YearTitle { get; set; }
        public string SaleTitle { get; set; }
        public string PurchaseTitle { get; set; }
        public Product ProductData { get; set; }
    }
    public class Product
    {
        public string Year { get; set; }
        public string Purchase { get; set; }
        public string Sale { get; set; }
    }
}

```

**Controller:**

```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using HealthHabitat.Models;

namespace HealthHabitat.Controllers
{
    public class ChartController : Controller
    {
        //
        // GET: /Home/

        public ActionResult Index()
        {
            ProductModel objProductModel = new ProductModel();
            objProductModel.ProductData = new Product();
            objProductModel.ProductData = GetChartData();
            objProductModel.YearTitle = "Year";
            objProductModel.SaleTitle = "Sale";
            objProductModel.PurchaseTitle = "Purchase";
            return View(objProductModel);

        }
        /// <summary>
        /// Code to get the data which we will pass to chart
        /// </summary>
        /// <returns></returns>
        public Product GetChartData()
        {
            Product objproduct = new Product();
            /*Get the data from databse and prepare the chart record data in string form.*/
            objproduct.Year = "2009,2010,2011,2012,2013,2014";
            objproduct.Sale = "2000,1000,3000,1500,2300,500";
            objproduct.Purchase = "2100,1400,2900,2400,2300,1500";
            return objproduct;
        }
    }
}

```

**View:**

```
 @model HealthHabitat.Models.ProductModel

<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">

    google.load("visualization", "1", { packages: ["corechart"] });
    google.setOnLoadCallback(drawChart);

    function drawChart() {
        // Create and populate the data table.
        var years = [@Model.ProductData.Year];
        var sales = [@Model.ProductData.Sale];
        var Purchase = [@Model.ProductData.Purchase];

        var data = new google.visualization.DataTable();
        data.addColumn('string', '@Model.YearTitle');
        data.addColumn('number', '@Model.SaleTitle');
        data.addColumn('number', '@Model.PurchaseTitle');
        for (i = 0; i < years.length; i++) {
            data.addRow([years[i].toString(), sales[i], Purchase[i]]);
        }
        var options = {
            title: 'Sale and Purchase Compare',
            hAxis: { title: '@Model.YearTitle', titleTextStyle: { color: 'red'} }
        };

        var chart = newgoogle.visualization.ColumnChart(document.getElementById('chartdiv'));
        chart.draw(data, options);
    }
</script>
<div id="chartdiv" style="width: 500px; height: 300px;">
