How to anonymize/mask part of string?

Say I am creating a pie chart for customer called 'Air Holland', for this customer I would like to show the overlap with other customers in a pie chart, including customers called 'Air Hungary', 'Air Ireland' and 'Air Iceland'. Due to privacy regulations of my customers I can only show partial names, e.g. the first three or four letters of their name. 'Air Holland' thus changes to 'Air xxxxxxx'

 

To implement this now in my pie chart, I have created a new Column CustomerNameMasked that takes the customer name, and replaces all characters but the first four with an 'x'. Ideally I would like to use CustomerName as the Legend in my pie chart, and then the CustomerNameMasked as the label, such that the pie chart is created using CustomerName, but will show the masked names.

 

However, as far as I know such a label is not possible, so now I have used CustomerNameMasked as my Legend column. But since these name are not unique (e.g. 'Air Hungary' and 'Air Holland' are both 'Air xxxxxxx' in the CustomerNameMasked column), different customers are taken together.

 

Any ideas how to create unique masked customer names? Or another work-around to ensure that my pie chart correctly shows the data per customer, but the legend shows masked names?

I would create a query that ingested the customer names and add an Index column to it. Then, when you create the anonymized names, just append the Index value and you will guarantee uniqueness.
