I am using ["angular-chart.js"](http://jtblin.github.io/angular-chart.js/)

and want to print this chart. My code is,

```
<html>
<head>Chart</head>
<body>
    <div class="row"><b>Patient Report</b>
        <div>
            <canvas id="line" class="chart chart-line" data="agedata" colours="colours"
                labels="labels" legend="true" series="series"click="onClick"></canvas>
        </div>
    </div>
    <div class="row">
        <a href="javascript:window.print()" class="btn btn-success">Print</a>
    </div>
</body>

```

But it prints nothing. Can Anyone suggest me methods to print chart?
