Simple way to anonymize all but selected customer name

[#1]

In a scatter chart...I would like to display, in the legend and pop up text, the customer name only for the selected customer either based on the customer name dimension or a list created from an island table of customer names which is then stored in a variable.  I tried using a calculated dimension:

if(customername = $(vSelectedCustomer), customername, hash128(customername))

but i get an error

Does anyone have a solution to this?  I am sure it has been done and is probably relatively simple.  Any help would be greatly appreciated.

First check the content of your variable, does it contain the selected customer? Then try enclosing your variable in single quotes:

if(customername = '$(vSelectedCustomer)', customername, hash128(customername))

thank you.  that definitely helped.  Now I am trying to format the text in the Legend to highlight the selected company and change the text for the hash128() values to light grey.  It appears to only work in a table for rows, not in the legend.  I added the expression to background to

if(customername = '$(vSelectedCustomer)', customername, green()) to the background format and did similiar for text format if not equal to variable value.  works perfectly when I fastchange to straight table but does not work in the scatter chart legend.
