Tableau api 获取相邻列字？

我想要的条件是，若maxcol1，那个么col2在tableau计算的feild中结束，输出将是e。

提前感谢

我已经用这些步骤尝试过了，看起来效果不错：

# first find the max. Using fixed lod calculation to do it across the whole dataset. The 1 is the same value across all so its doing a group max, but the group is the full data
MaxCol1: {fixed 1: MAX(Col1)}

# pick out rows where max is found in Col1
Col1Match: Col1=[MaxCol1]

# find Col2 where there's a match and fill rest with NULL's
Col2Value: IF [Col1Match] then Col2 else NULL end

# This will be a bunch of NULL's and "e"
# Finally, do the same as in the first calculation to get the result
Output: {fixed 1 : max([Col2Value])}

现在，您可以尝试将这些步骤结合起来，稍微清理一下空间。这就足够了，还是您的真实数据更复杂

最好的，

简单地使用

If [col1] = {max([col1])} then col2 end

将此项放到视图中并隐藏空值，您将获得所需的值。

只需使用

If [col1] = {max([col1])} then col2 end

如果两个值在第二列中用c映射，会怎么样？或者您确定只有一个这样的值吗？如果两个值在第二列中用c映射会怎么样？或者您确定只有一个这样的值吗
