Google 堆叠图表 bar/column 整个柱状图的图表注释

Question

我在 Google 图表中制作了堆叠式 column/bar 图表，但我在格式化 "whole" 条形图的注释时遇到问题（意味着每列的每个条形图相加） . 不知何故格式化不起作用，如果我使用 "getFormattedValue()" 计算被搞砸了。有人有建议吗？我希望将数字缩短为短格式（80k 而不是 80.000）

非常感谢！

使用格式化程序方法 --> formatValue -- 格式化单个值...

    var value = 0;
    for(var u = 1; u < dt.getNumberOfColumns(); u++) {
      value += dt.getValue(row, u);
    }
    return formatter.formatValue(value);
