Measure to divide each data point by the earliest visible data point
Probably an easy one for someone out there.
I have some time series data and I want a measure where it forces the result to be 1 on the first time shown in the graph.
So basically it would show the value of the items divided by the first date visible in the report. And when I change the slider to show other dates it changes the value it is dividing by to the one for that start date.
I was using this formula in a column - but this just refers to the first EVER date as opposed to the first visible one.
LME N = [LME]/calculate(average([LME]) ,filter('Copper',[Date]= min([Date])))
ScottPat , Try like
LME N =
var _min = minx(allselected('Copper'), [Date])
return[LME]/calculate(average([LME]) ,filter('Copper',[Date]= _min))
prefer a date table joined with date of your table
LME N =
var _min = minx(allselected('Date'), [Date])
return[LME]/calculate(average([LME]) ,filter('Date',Date[Date]= _min))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.

Refer :radacad sqlbi My Video Series Appreciate your Kudos. Now I get " the value for 'LME' cannot be determined."
I guess this is about row context but not sure how to fix - i ofcourse want the LME value to use each time periods value.

ScottPat , My mistake LME is a measure
LME N =
var _min = minx(allselected('Copper'), [Date])
returndivide([LME], calculate(averagex(Values('Copper'[Date]), [LME]) ,filter('Copper',[Date]= _min)) )
or
LME N =
var _min = minx(allselected('Copper'), [Date])
returndivide([LME], calculate(averagex('Copper', [LME]) ,filter('Copper',[Date]= _min)) )
or use a avg measure
No LME is a column not a measure (with the sigma / Sum icon) - so it still doesn't seem quite right in my context.
