title: Google charts not showing axis labels
body: <p>This is not for the image charts. <br> I have the following code that generates the right chart but the labels don't show. The chart div is in an other div that is used as a tab on my page. <br> When I run the function when the tab containing the chart is not selected, the chart appears with no labels. When I run the function with the tab selected, the labels appear.</p>
  
  <pre><code>  drawChart()
    }
  
     function drawChart() {
      var data = new google.visualization.DataTable();
      data.addColumn('string', 'Weeks');
      data.addColumn('number', 'Indice');
  
      data.addRows(arrIndice1);
  
      var options = {
        width:"900",
