Help to build ABC Chart (Pareto)

[Nemo1]

So my dream is to build the graph below... I will explain further because my drawing kinda sucks. 🙂 

I want to build a graph, paretto style, that classifies CITIES according to their %Acc Sales. The 10% of cities where the most sales where made should be classifies as 1, the other 20% as 2, and then the rest as 3:

I have two problems: 

1- in the x axis I can only display the cities sorted from the ones where the biggest sale where made to the ones where the lowest sale was amde. (I could sorted according to their sales in a descending order)

2- I do now know how to add lines to the graph that mark where the "1" cities start in the x axis, where the "2" cities start and the "3"... i would like to mark that and what % of sales they made. 

what I managed to do: 

what I want to do:

I hope that was clear.. it is not easy to explain. I am not good at explaining myself, I will create another question soon and I will ask chatgpt to help me explain myself better.. in case you wanna check the other question out, i will leave the link below..

thanks everyone 😄
