我正在使用Google Visualizations构建一个仪表板，它将以图表，时间序列和表格形式显示许多不同的数据集合（为了完整起见，html是由Python生成的，尽管我不认为这与我的问题有关）。我自己处理表格，它们工作正常，我还没有实现图表，尽管我为之前的迭代构建了略微不同的图表。有了上下文，我的问题来自时间序列：页面成功显示过滤器（即“度量”和“类别”及相关的下拉列表），但不是行图，并给出错误“一个或多个参与者没能画（）。“每次选择过滤器时，都会显示另一个相同的错误。
这是我的（匿名）代码，带有相关的html：

<script type="text/javascript">

我查看了stackOverflow和Google Groups档案，我找到了其他有这个问题的人，虽然从我能说的问题和解决方案与我所面临的不同。最后，我还没有真正使用除了似乎可能解决我的问题的选项之外的选项，所以我并不特别关心这些图表的可读性，而是实际创建这些图表。谢谢！
答案 0 :(得分：0)
折线图的ChartWrapper中有一个拼写错误：containterId不应该有两个t。将其更改为containerId，您的代码可以正常运行。
