在脚本标签中,我添加了以下代码,我无法为其设置动画.善意的suugest

  google.load("visualization", "1", {packages:["corechart"]});
  google.setOnLoadCallback(drawChart);
  function drawChart() {
    var data = google.visualization.arrayToDataTable([
      ['Year', 'Sales', 'Expenses'],
      ['2004',  1000,      400],
      ['2005',  1170,      460],
      ['2006',  660,       1120],
      ['2007',  1030,      540]
    ]);

    var options = {
      title: 'Company Performance',
       animation: {
          duration: 1000,
          easing: 'out'
      },
      vAxis: {title: 'Year',  titleTextStyle: {color: 'red'}, minValue:0, maxValue:1000}
    };
    var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
    chart.draw(data, options);
  }
