title: vue chart js not showing in print preview
body: <p>hi i am using vue chartjs <a href="https://www.npmjs.com/package/vue-chart-js" rel="nofollow noreferrer">link of npm package</a> in my project.</p>
  
  <p>the chart is working fine, but when i am trying to print a div where multiple charts are implement using the following code </p>
  
  <pre><code>let divContents = $("#exportDiv").html();
  let printWindow = window.open('', '', 'height=400,width=800');
  printWindow.document.write('&lt;html&gt;&lt;head&gt;&lt;title&gt;Report&lt;/title&gt;');
  printWindow.document.write('&lt;link rel=\"stylesheet\" href=\"css/style.css\" type=\"text/css\" /&gt;');
  printWindow.document.write('&lt;link rel=\"stylesheet\" href=\"css/bootstrap.min.css\" type=\"text/css\" /&gt;');
  printWindow.document.write('&lt;/head&gt;&lt;body &gt;');
  printWindow.document.write(divContents);
  printWindow.document.write('&lt;/body&gt;&lt;/html&gt;');
  printWindow.document.close();
  setTimeout(function(){printWindow.print();},1000);
  </code></pre>
  
  <p>in preview window i am not seeing chart.</p>

  <p>Note: chart is not showing only when i am calling print on button click, if i am pressing ctrl+p chart is showing. but i want only a particular div to print so i cannot use ctrl+p.</p>
  
  <p>what am i doing wrong?</p>
  
  <p>i am declaring it </p>
  
  <pre><code>&lt;vue-chart type="doughnut" :height="100" :options="optionsInvestorResearch" :data="chartInvestorResearch"&gt;&lt;/vue-chart&gt;
  </code></pre>
  
  <p>and my optinons are</p>
  
  <p>chartInvestorResearch: {},
  optionsInvestorResearch: {</p>
  
  <pre><code>title: {
          display: false,
          fontsize: 14,
          text: 'Total de Pedidos por Situação'
      },
      legend: {
          display: true,
          position: 'right',
      },
  },
  </code></pre>
  
  <p>update: i included my chart declaration and option.</p>
