使用下拉菜单限制 Spotfire 数据

Question

我有一个带有两个下拉列表的 spotfire 仪表板，一个用于日，一个用于月，我想用它来限制可视化的数据。

我需要能够同时使用两个过滤器。我目前写了一个 case 语句来执行此操作，但是 case 语句在默认情况下会在表达式达到 true 语句时停止计算表达式。
例如下面，我在顶部有 MonthSelector 的语句，它不会继续评估 DaySelector。

case

when "${MonthSelector}"="all" then [Month] <> ''

when "${MonthSelector}"<>"all" then [Month] = "${MonthSelector}"

when "${DaySelector}"="all" then [Week_Day] <> ''

when "${DaySelector}"="WeekDay" then [Week_Day] <> 'Saturday' and [Week_Day] <> 'Sunday'

when "${DaySelector}"="WeekEnd" then [Week_Day] = 'Saturday' OR [Week_Day] = 'Sunday'

when "${DaySelector}"<>"WeekEnd" AND "${DaySelector}"<>"WeekDay" AND "${DaySelector}"<>"all" then [Week_Day] = "${DaySelector}"
else false end case

我需要帮助以某种方式让 spotfire 继续评估超过第一个 true 的 case 语句，或者以另一种方式编写数据限制表达式，该表达式将基于两个下拉列表限制数据。

我很茫然，任何帮助将不胜感激。

你能尝试嵌套案例吗？也许喜欢这个未经测试的表达：

case
    when "${MonthSelector}"="all" then case
        when "${DaySelector}"="all" then [Week_Day] <> '' and [Month] <> ''
        when "${DaySelector}"="WeekDay" then [Week_Day] <> 'Saturday' and [Week_Day] <> 'Sunday' and [Month] <> ''
        when "${DaySelector}"="WeekEnd" then [Week_Day] = 'Saturday' OR [Week_Day] = 'Sunday' and [Month] <> ''
        when "${DaySelector}"<>"WeekEnd" AND "${DaySelector}"<>"WeekDay" AND "${DaySelector}"<>"all" then [Week_Day] = "${DaySelector}" and [Month] <> ''
        else false
        end
    when "${MonthSelector}"<>"all" then case
        when "${DaySelector}"="all" then [Week_Day] <> '' and [Month] = "${MonthSelector}"
        when "${DaySelector}"="WeekDay" then [Week_Day] <> 'Saturday' and [Week_Day] <> 'Sunday' and [Month] = "${MonthSelector}"
        when "${DaySelector}"="WeekEnd" then [Week_Day] = 'Saturday' OR [Week_Day] = 'Sunday' and [Month] = "${MonthSelector}"
        when "${DaySelector}"<>"WeekEnd" AND "${DaySelector}"<>"WeekDay" AND "${DaySelector}"<>"all" then [Week_Day] = "${DaySelector}" and [Month] = "${MonthSelector}"
        else false
        end
    else false
end
