Zing 图表堆积图

Question

我正在使用 Zing Chart 堆积条形图。我正在从 Oracle 数据库加载数据来填充图表。我有两个堆栈：打开和关闭。我想在堆栈顶部显示打开文档到关闭文档的数量 Open:Closed（例如 5:303）。我能够在单个堆栈的顶部打印数字（封闭栏顶部 5，开放栏顶部 303）但我想在最顶部显示它们，因为如果有 1 个打开和 0 个关闭，数字相互重叠，无法读取。因此，我一直在查看 Zing Charts 提供的所有 JSON 标记，但我无法找到一种方法来获取每个数字（值）并将它们一起显示。

Answer 1

您可以通过绘图和节点索引来访问节点值。例如，(%node-value)(0)(4) 将为您提供第一个图上第 5 个节点的值。

由于堆叠条形图在技术上是 2 个图，您可以在第二个（打开）图中使用以下标记：

"text":"%node-value:(%node-value)(0)"
