  <p>representing a date / hh:ss in haxis and visitors in Yaxis.</p>
  
  <p>my script code is as follow:</p>
  
  <pre><code>  &lt;script&gt;
     google.load("visualization", "1", {packages:["corechart","table"]});

          var options = {

          };
  
          var productAllocationChartBO99 = new google.visualization.LineChart(document.getElementById('product-allocation-chartBO99'));

  <p>I understand from this <a href="https://developers.google.com/chart/interactive/docs/datesandtimes#formatting-axis-gridline-and-tick-labels" rel="nofollow">google documentation</a> that i should have specific options for haxis matching my date format, or potential change my json to match a google chart format.</p>
  
  <p>What is your recommendation to solve this?</p>
  
  <p>Thanks</p>
