Question

我正在使用amCharts的堆积柱形图。它为堆叠条形中的条形部分添加数字标签。

如何在堆栈顶部添加每个柱的总数？

例如，如果图表中的第一列有五个parititions，如下所示：第一个分区的大小（高度）：5 第二个分区的大小（高度）：11 第三个分区的大小（高度）：14 第四个分区的大小（高度）：20 第五分区的大小（高度）：21

我现在得到这些标签。但是，我还想在第一列（堆积条）的顶部贴上标签，上面写着71。通过添加5,11,14,20和21获得71。

要回答部分问题，您可以添加

"titleText":"[[total]]"

选项"valueAxes"，即：

"valueAxes": [{
        "stackType": "regular",
        "axisAlpha": 0.3,
        "gridAlpha": 0,
        "totalText": "[[total]]"
    }],

这将显示每个堆栈顶部的总计。至于添加“这是获得的”部分......祝你好运。
