Extracting / Plotting values in the last column

[Anonymous]

Hi everyone

I have a table of account balances by date, in the following format:

Account	01/01/2021	02/01/2021
A	£20	£34
B	£23	£45
C	£34	£56

I would like to populate a matrix with the values for the latest date - ie those in the last column. At the moment if I populate the matrix it uses the sum of all dates for each account.  

Similarly if I plot the account value over time I only have the option to plot the sum for all periods for each account not the values on individual days.

As a second step, probably too ambitious for me at the moment, I would like to compute the change in value of each account over the last day/week/month/year.

This will be complicated by the fact that the data is only stored monthly prior to this calendar year, but I am happy to use this monthly value as the average for the month to get things moving.

Any help would be very much appreciated

Kind regrads

@Anonymous , Unpivot the data .

Assume it will create date and value   column

Create a measure like for last date

Meausre =

var _max = maxx(allselected(Table), Table[Date])

Return

calculate(Sum(Table[Value]), filter(Table, Table[Date] =_max))

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.

Perfect many thanks I just need to bug you with for the idiots guide to syntax within the measure.

Unpivot went well, but I have made quite a few 🙂 attempts to enter the code as descirbed before bothering you again but I get an error message that the syntax is wrong. 

The screen gives me:

The actual text enlarged is

 and the error message 

Many thanks

Having spotted the missing ' in line 2, I still get unexpected expression for [Value] and [Date] on line 2.

Hi @Anonymous going to suggest that you unpivot those columns in Power Query to create a date field instead.  Then it should be fairly easy to do the things you indicated.
