tc-angular-chartjs doesn't appear at loading
<p>I have a line chart which doesn't appears at the loading of the page but only appears on hover, it's very strange. I thought I had forgotten some options but i also paste the code of the web site <a href="http://carlcraig.github.io/tc-angular-chartjs/line/" rel="nofollow">http://carlcraig.github.io/tc-angular-chartjs/line/</a> in my programm. I still have the problem... 
any ideas please?</p>
