title: Chart.js not loading on reload
body: <p>I'm having a pretty strange issue with Chart.js in Meteor.</p>
  
  <p>I have one chart on the page that gets its data using <code>Session.get('values');</code> to get their information. This works fine if you change routes using the menu. However if you push the reload button on the page the chart loads in but the data doesn't, if I hover over the data points on the chart it just shows the label without any number or anything. </p>
  
  <p>If I run the <code>Session.get('values');</code> in the console it returns the data fine, and as soon as I click a menu item and then click back on the one with the chart in it, it loads fine!  </p>
  
  <p>I am using <code>Template.templatename.onRendered();</code> to load in the chart data otherwise the chart doesn't load at all.</p>
  
  <p>Any help is appreciated! </p>
