title: Test a Chart.js canvas with Protractor
body: <p>I'm fairly new to protractor so sorry if this is a stupid question. I'm looking into testing an application and need test the values inside a Chart.js graph.</p>
  
  <p>Has anyone got any ideas on how to get  my protractor program to look inside the canvas.</p>
  
  <p>This is the canvas output in HTML.</p>
  
  <pre><code>&lt;canvas id="test" 
          class="chart chart-line ng-isolate-scope" 
          data="test.data" 
          labels="test.labels" 
          series="test.series" 
          legend="true" 
          options="test.options" 
          colours="test.colours" 
          width="1816" 
          height="800" 
          style="width: 908px; 
          height: 400px;"&gt;
  &lt;/canvas&gt;
  </code></pre>
  
  <p>Thanks in advance.</p>
