获取超出过滤器范围的值

Question

我正在处理一个表格项目，其中包含显示开始月份、结束月份和每月费用的长格式表格数据。我试图显示日期的每月成本（动态）范围的视觉效果，然后覆盖多月行总成本的参考线。我怀疑答案在于使用细节层次 (LOD) 表达式，但似乎无法弄清楚。

示例 csv：

start,end,month length,x,a,b,c,d,total
1/1/2019,1/1/2019,1,1.2,0.08,0.01,0.1,0.299,0.489
2/1/2019,2/1/2019,1,1.1,0.08,0.01,0.1,0.295,0.485
3/1/2019,3/1/2019,1,0.9,0.08,0.01,0.12,0.285,0.495
1/1/2019,2/1/2019,2,2.3,0.08,0.01,0.1,0.297086956521739,0.487086956521739
2/1/2019,3/1/2019,2,2,0.08,0.01,0.109,0.2905,0.4895
1/1/2019,3/1/2019,3,3.2,0.08,0.01,0.105625,0.2936875,0.4893125

忽略 x,a,b,c,d - 它们将显示图表有多个等于月度总数的度量。

对于相同的开始和结束月份，我们有一个month length: 1。与这些行关联的值是每月值。为了绘制月份的动态范围，我可以通过过滤 month length: 1 并添加计算字段过滤器来将开始日期设置为结束日期范围 [Start Date] >= [Selected Start Date] AND [Start Date] <= [Selected End Date] 来绘制这些月度值。

鉴于此表，即使存在过滤器month length: 1?这里的最终结果将是一行0.4893125

是的，你是对的，你需要使用 LoD。

如果您需要绕过过滤器，请使用 LoD Fixed，下面的代码 sn-p 将为您提供 month = 3 的数据，尽管过滤器是 month=1。根据您的要求更改代码：

{ FIXED : Max(IF [Month Length] = 3 THEN [A] END)}

编辑---------------------------------------------- ------------------------------------

{ FIXED : 
Max(
IF ([Start Date] >= [Selected Start Date] AND 
[Start Date] <= [Selected End Date]) AND
[Month Length] = 3 THEN [A] END)}
