title: Google timeline - how to include a vertical line with current date
body: <p>I have a timeline in google created since a spreadsheet but I can´t include a vertical line to show the current date. Appreciate any help.</p>
  
  <p>The code that is generating the timeline is:</p>
  
  <pre><code>&lt;html&gt;
    &lt;head&gt;
      &lt;script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"&gt;&lt;/script&gt;
      &lt;script src="chart.js"&gt;&lt;/script&gt;
      &lt;script type="text/javascript"&gt;
        google.charts.load('current');
        var myStoredString = '{"containerId": "example3.1",' +
          '"dataSourceUrl": "https://docs.google.com/spreadsheets/d/13O7jpSMh1c9GcvP4FeFQr3ehiVYhRRoVGwkSN2SyoAY/edit#gid=0",' +
            '"query":"SELECT A,B,D,E",' +
          '"chartType": "Timeline",' +
          '"options": {' +
          '   "alternatingRowStyle": true,' +
          '   "colorByRowLabel": true,' +
          '}' +
        '}';
        function drawVisualization() {
          google.visualization.drawChart(myStoredString);
        }
        google.charts.setOnLoadCallback(drawVisualization);
      &lt;/script&gt;
      &lt;div id="example3.1" style="height: 240px;"&gt;&lt;/div&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
