Default Date

Hi Anonymous 

Dynamically show today's value by default by slicer is not supported in power bi.

In addition to  amitchandak's reply, you can try to build a measure filter and add this filter into filter pane as well.

Measure = IF(MAX('Table'[Date])>= DATE(YEAR(TODAY()),01,01) && MAX('Table'[Date])<=TODAY(),1,0)

Set this filter to show items when value =1.

However if you use this measure filter in your visual, it won't show values after today or before start day.

I update a new measure, build a date table for slicer.

Measure1 = 
VAR _MINDate = MIN('Date'[Date])
VAR _MAXDate = MAX('Date'[Date])
Return
IF(MAX('Table'[Date])>=_MINDate && MAX('Table'[Date])<=IF(_MAXDate>=TODAY(),_MAXDate,TODAY()),1,0)

By this measure it will show dynamic result by slicer.

If we change slicer from 2020/12/01 to 2021/02/19, it will show result we want.

Due to you use Between in slicer, this measure has a disadvantage that if the maxdate in slicer >Today when you open your report, it will show you values in maxdate instead of today.

I had same issue. This is what I did if it helps.

I added calcuated column 

Is-Today = IF(MyDateTable[Date] <= TODAY(), "True", "False"). 

 

then i filtered as follows

 

It works perfectly fine for me.
