Stacked graph with counted reference line

[matthewp]

I am trying to re create this graph but cannot get the reference line to work.

I want spend up the y axis (expression: SUM(spend)), then across the x axis i want supplier name and it stacked by supplier group.

Now the difficult part, i want to have a variable which can be set from a slider between 1 to 100 (not difficult) which will be used in an x axis reference line that splits it by count([supplier name]) and the reference line text shows what percentage of the spend is in that percentage of suppliers.

For example the example below the variable is set to 20, so i want the reference line to be set on the x axis to 20% of the total suppliers used and then the reference line text is calculated that 20% of the suppliers = 80% of the spend.
