Question

情况： 我想显示最近两个月的平均每日工作时间，两个月之间的差额。

我的DAX措施：

Sessions_Curr = AVERAGEX('Table','Table'[Sessions]) 
    //Calculates the average per grouping
Sessions_Prev = CALCULATE(
    'Table'[Sessions_Curr],
    PREVIOUSMONTH('Date'[Date])
     ) // Calculates the average for the previous month.
Diff Sessions = Sessions_Curr - Sessions_Prev // Difference between the two previous measures.

接下来，我添加一个可视级别过滤器：最近2个日历月的相对日期过滤。到目前为止一切正常。

目标：

但是我不希望第二个月显示出差异，因此，单元格空白即：像这样

+---------------+----------+------+
|   date        | sessions | diff |
+---------------+----------+------+
| 2019 february |     1000 |      |
| 2019 march    |     1500 |  500 |
+---------------+----------+------+

精算结果：

+---------------+----------+------+
|   date        | sessions | diff |
+---------------+----------+------+
| 2019 february |     1000 | -200 |
| 2019 march    |     1500 |  500 |
+---------------+----------+------+

Answer 1

尝试此操作-它仅显示最近选定月份的度量：

Diff Sessions = 
VAR ContextDate = LASTDATE( 'Date'[Date] )
VAR LatestSelectedDate = LASTDATE( ALLSELECTED ( 'Date'[Date] ) )
RETURN
    IF ( 
        FORMAT ( ContextDate, "YYYY-MM") = FORMAT ( LatestSelectedDate, "YYYY-MM" ),
        [Sessions_Curr] - [Sessions_Prev],
        BLANK()
    )
