If you use the LAST() function you can isolate the end value on a continuous axis. In this instance, the calculation should look like:
IF LAST()=0 THEN RUNNING_SUM(COUNT([Sc Id])) END
This will return only the final value of the running sum of the count of Sc Id. You can then use this calculation on a dual axis with RUNNING_SUM(CNT(Sc Id)).
From here you can edit size and formatting to rearrange the label to be inside the circle. Please see attached workbook for solution.
Hope this helps!
