我想显示3个图表和一个控制器。我有一个图表和一个控制器。现在我需要使用相同的数据库（电子表格链接）来创建除饼图，示例条形图或折线图之外的其他两个图表或....我的代码到目前为止。
我最近开始使用javascript，这只是我的第一周，所以我不知道如何让它工作。任何帮助表示赞赏。
P.S。您可以使用任何您想要的图表列。

答案 0 :(得分：0)
如果使用相同的数据源，则只需在与现有图表相同的功能中添加更多图表...
请务必添加容器<div>
并且仪表板将采用一系列控件和/或图表......
dashboard.bind(donutRangeSlider, [pieChart, colChart, lineChart]);
请参阅以下工作代码段...
