Chart.js in ASP.NET, Data from database

I am currently working on the last page of my web form, which is the Dashboard. I followed this guide: http://ift.tt/1pOh5Op to implement chart.js graphs into my dashboard but it only shows me how to manually add data in. I am looking to have my axis and data points be pulled from the database. I've search around and just cant find out how to get the data directly from the database. If anyone could guide me in the right direction, that'd be much appreciated!
