I think the second dimension is confusing the accumulation option in the expressions box. You can try using a combination of Rangesum() and above() functions to get the desired result.
returns the count of the process_starts cumulatively (without having the accumulation on as an option in the expressions dialogue)
You can then tweak this to get the other results.
for the averagetime
Letme know if this works,
This works, but there is a snag. As there is a lot of data I need to group my table by month, and when I do this I lose the cumulative average.
I have attached an example
Test_Cumm_Avg_qv2.qvw 156.5 K
Can't check this out in depth just yet but it might be becaues of the "total" function (aggregating it over the whole table instead of month)
In the functions. This will evalutate the function over all the values in the group betewen the <>, ie by month
