[Chartjs]-Chart.js shows no graphs

You are missing creating chart itself:

var myChart = new Chart(chartData.ctx).Line(chartData.chart); //'Line' defines type of the chart.

You are only defining how the object should look like but you forgot to create it itself.

Follow CANVAS tutorial to add graph in DOM. http://www.williammalone.com/articles/html5-canvas-javascript-bar-graph/
