title: multiple chartjs in the same page
body: <p>hi i was trying to use chartjs 
  can be found in this link <a href="http://www.chartjs.org" rel="noreferrer">www.chartjs.org</a></p>
  
  <p>i tried to draw two chart in the same page using the samples code</p>
  
  <p>i created two different div with two different ids</p>
  
  <p>like this </p>
  
  <pre><code>&lt;div id="chart1"&gt;&lt;/div&gt;
  &lt;div id="chart2"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>then after including this line :
      
      </p>
  
  <p>i created the first chart this way:</p>
  
  <pre><code> window.onload = function(){
      var ctx1 = document.getElementById("chart1").getContext("2d");
      window.myLine = new Chart(ctx1).Line(lineChartData, {
          responsive: true
      });
  }
  </code></pre>
  
  <p>and the second chart this way :</p>
  
  <pre><code>   window.onload = function(){
          var ctx2 = document.getElementById("chart2").getContext("2d");
          window.myPie = new Chart(ctx2).Pie(pieData);
      };
  </code></pre>
  
  <p>data used for both chart is the same like as samples , so nothing changed
  but if i draw just one chart by itself it works great
  if i put the two chart at the same time i get only the pie chart </p>
  
  <p>can you tell me where is the problem please
  i think it is some sort of conflict , but i can't find it</p>
