谷歌图表不显示IE-9

我的网页上有谷歌图表。所有值均由 php 脚本生成。但是在IE-9图表上没有出现（空白的地方）。适用于 IE-11。

<script type="text/javascript" src="jsapi.js"></script>
   <script type="text/javascript">
      google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
  var data = google.visualization.arrayToDataTable([
    ['Date', 'Name1',        'Nane2',            'Name3,                'Name4',          'Name5',             'Name6',             'Name7',        'Name8',             'Name9'],
    ['',  <?php echo $E; ?>,       <?php echo $B; ?>,     <?php echo $H; ?>,      <?php echo $Q; ?>,      <?php echo $M; ?>,      <?php echo $F; ?>  ,   <?php echo $O; ?>,   <?php echo $R; ?>,          <?php echo $OTR; ?> ],
  ]);
  var options = {
    title: 'Downtime Report',
    vAxis: {title: 'Downtime Minutes', titleTextStyle: {color: 'red'}
    }
  };
  var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
  chart.draw(data, options);
}
    </script>
