Hi,

I have a bar chart which shows bars with numbers based on different types of products sold per month, like in Feb we have 3 bars for every product type being the quantities 57, 9, 167. I would like to show the percentages 24%, 3%, 71%

The math is the following:
count by value / Sum of all items * 100

I'm using the (count by value) aggregator but that shows just the plain count
