Google图表数组 - 第0行的行类型无效

Question

第一次使用Google图表API以及我在这里获得的所有内容我会想象它的工作原理。但是，当我查看Chrome控制台时，出现错误invalid row type for row 0。试图环顾四周，为什么会发生，但我不能完全弄清楚。

如果有帮助，here是我基于所有这一切的教程。

这里是我的代码：

<script type='text/javascript'> 
    google.load('visualization', '1', {packages: ['corechart']}); 
</script> 

<script type='text/javascript'> 
    function drawVisualization() { 
     var gdata = google.visualization.arrayToDataTable(['TurbTemp_F'], ['45.68'], ['45.68'], ['45.86'], ['45.86'], ['45.86'], ['45.86'], ['45.86'], ['45.86'], ['45.86'], ['45.5'], ['45.5'], ['45.68'], ['45.86'], ['45.86'], ['46.04'], ['46.22'], ['46.4'], ['46.58'], ['46.58'], ['46.76'], ['46.94'], ['47.12'], ['47.12'], ['47.3'], ['47.66'], ['47.66'], ['47.66'], ['47.84'], ['48.02'], ['48.02'], ['48.02'], ['48.2'], ['48.38'], ['48.74'], ['48.74'], ['48.92']); 
     var options = { 
      title: 'Title here', 
      vAxis: { title: 'vvv' }, 
      seriesType: 'bars', 
      series: { 
       3: { type: 'area' } 
      } 
     }; 
     var chart = new google.visualization.ComboChart(document.getElementById('chart_div')); 
     chart.draw(gdata, options); 
    } 
    google.setOnLoadCallback(drawVisualization); 
</script> 

任何帮助将不胜感激！谢谢！

你忘了周围[]在GDATA 应

var gdata = google.visualization.arrayToDataTable([['TurbTemp_F'], ['45.68'], ['45.68'], ['45.86'], ['45.86'], ['45.86'], ['45.86'], ['45.86'], ['45.86'], ['45.86'], ['45.5'], ['45.5'], ['45.68'], ['45.86'], ['45.86'], ['46.04'], ['46.22'], ['46.4'], ['46.58'], ['46.58'], ['46.76'], ['46.94'], ['47.12'], ['47.12'], ['47.3'], ['47.66'], ['47.66'], ['47.66'], ['47.84'], ['48.02'], ['48.02'], ['48.02'], ['48.2'], ['48.38'], ['48.74'], ['48.74'], ['48.92']]); 

这将产生另一个错误“给没有足够的列绘制图表要求。”我添加另一列，然后错误的值作为字符串，所以我最终与

var gdata = google.visualization.arrayToDataTable([['Day','TurbTemp_F'], ['1',45.68], ['2',45.68], ['3',45.86], ['4',45.86], ['5',45.86], ['6',45.86], ['7',45.86]]);
