【问题描述】：
我正在尝试使用 Google 可视化工具创建仪表板，但遇到了一些问题。
我通过在 ChartWrapper 中设置 calc 属性来引入所有文本的数据并即时计算图表数据，当数据表准备好时，我调用一个函数来设置图表的视图。完整代码如下。
我遇到的问题是：
- 使用控件过滤表时出现无效行索引错误。一旦设置视图并重新绘制图表，这些就会消失，但“一个或多个参与者未能绘制（）”错误仍然存在。
- 第一次加载时，图表与视图设置之前的原始数据一起显示。
- 我返回带有数字的文本数据（即“1. Male”），因此列排序正确，但我不想在图表中看到数字。关于如何清理标签的任何想法？
任何帮助将不胜感激。如果您对处理此类数据的更好方法有任何建议，我会全力以赴。
