Chart.js V2.1.4 does working, with backbone view - backbone.js

Question

I want to use a upgraded version of Chart.js v2.1.4 with Backbone View(working fine with v1.0.2) as because of additional features.But it not working with upgraded version v 2.1.4.
Code snippet are:
define([
'underscore',
'jquery',
'backbone',
'Chart',
'text!templates/dashboard/graph-view-template.html'
], function(_, $, Backbone, Chart, GraphViewTemplate) {
var GraphView = Backbone.View.extend({
template: GraphViewTemplate,
events: {
},
elements: {
},
initialize: function(options){
this.options = options;
},
render: function(){
this.$el.html(this.template);
this.renderTempGraph();
return this;
},
renderTempGraph: function(){
var ctx = this.$el.find("#myChart").get(0).getContext("2d");
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ["Red", "Blue", "Yellow"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
}
});
}
return GraphView;
});
<canvas id="myChart" width="400" height="400"></canvas>
after render, canvas element properties look like as
<iframe class="chartjs-hidden-iframe" style="width: 100%; display: block; border: 0px; height: 0px; margin: 0px; position: absolute; left: 0px; right: 0px; top: 0px; bottom: 0px;">
</iframe>
<canvas id="myChart" width="0" height="0" style="width: 0px; height: 0px;"></canvas>
