Google 可视化仪表板错误

【中文标题】Google 可视化仪表板错误【英文标题】:Google Visualization Dashboard Errors 【发布时间】:2017-04-21 09:55:49 【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。

【问题讨论】:
【参考方案1】:1 & 2) 可以通过断开charts
与dashboard
的连接来纠正这些问题
charts
可以在'ready'
事件在table
上触发时独立绘制,
使用来自table
图表的过滤数据
这将防止错误和首次加载时绘制初始原始数据
3) 自定义排序标签,在数据数组 中使用对象表示法
数据表中的每个单元格都必须有一个值(v:
),
并且可选地,可以有一个格式化的值(f:
)
在数据数组中,而不是使用 --> "1. Male"
改为使用对象表示法 --> v: "1", f: "Male"
注意:图表默认显示格式化值
但是,CategoryFilter
上必须设置两个选项
设置选项 --> useFormattedValue: true
-- 在控件中显示格式化值
设置选项 --> ui.sortValues: false
-- 显示在数据中找到的类别
请参阅以下工作 sn-p
数据中的前两列已更新为使用上述对象表示法...

完美运行。谢谢。以上是关于Google 可视化仪表板错误的主要内容,如果未能解决你的问题,请参考以下文章
