当前代码:
Rebase3 =
VAR BASELINE_VALUE = CALCULATE(SUM('Equity Markets (2)'[[Value]), FIRSTDATE(ALLSELECTED('Equity Markets(2)'[Date])))VAR VALUE_TO_COMPARE = SUM(“股票市场(2)'[值])
返回
DIVIDE(VALUE_TO_COMPARE,BASELINE_VALUE)
答案 0 :(得分:2)
我简化了您的姓名,仅以S&P500(第二个索引)列为例-其他人的工作方式相同。
创建度量:
Rebased S&P500 =
VAR
Original_Value =
CALCULATE ( SUM ( Data[SP500] ), FIRSTDATE ( ALLSELECTED ( Data[Date] ) ) )
VAR
Current_Value = SUM ( Data[SP500] )
RETURN
DIVIDE ( Current_Value, Original_Value )
结果(我使用了Power Pivot表,但是Power BI中的图表将以相同的方式工作):

感谢您是新手,您在这里创建了一些众所周知的新手错误。
第一个是使用VAR。这非常重要,而且也是违反直觉的。定义VAR后,它实际上是一个常数,不会因用户的选择而改变!。这样做的原因是您丢失了上下文(DAX中的所有查询都存在于context中)。解决方案是定义一个MEASURE。一旦这样做,就可以解决问题。这就是为什么您会得到垃圾结果。

好消息是,一旦您了解了这一点,就可以解决DAX中最困难的障碍。
