Whale Curve with percentage of customers on x-axis

[Anonymous]

Hello!
I have a dataset that consists of 3 columns (Customer_name, Sum of sales, Count of purchases). I'm trying to create a whale curve with percentages of customers on x-axis from most contributing customers to sales and number of purchases to least contributors.
On y-axis I'd like to have two measures(lines) % of running total of sum of sales and % of running total of count of purchases.
I'm more of a Tableau user, and this grapf can be reached by this method Discover the Winners and Losers within your Customers using a Whale Curve! (biztory.com)
How can achieve this in Power BI? Could you help?
Here's the table I'm using.

Customer Name	Sum of SALES	Count of Purchases
customer 1	$1,444,864	919
customer 7	$651,757	51

 a whale curve with percentages of customers on x-axis from most contributing customers to sales and number of purchases to least contributors.
On y-axis I'd like to have two measures(lines) % of running total of sum of sales and % of running total of count of purchases.

How is that a whale curve?  Sounds more like two independent histograms.

Visualizing customer profitability with the whale curve - Baker Tilly

Maybe this is closer to what you want?

It plots the cumulative percentage of sales versus the cumulative percentage of contributing customers.

You would need customers with negative sales to get a whale curve.
