Cumulative distinct count across multiple dimensions in QlikSense

Question

I'm trying to count distinct cumulatively with two dimensions.

I have tried the below code which does work when there is only a single dimension, however this does not work with multiple dimensions.

Rangesum(Above(Count( distinct [FieldName]),0,RowNo()))

FYI - attempting this within a line chart

Answer 1

A temporary answer to this is to remove the second dimension and amend the measure.

Rangesum(Above(sum( if(Dimension=1,Measure)),0,RowNo()))

However this does require a separate measure for each possible value in the dimension.
