The thousands separator format is sensitive to the current locale.
I do not know of any way to set is separately; only as one component
of a full numerical locale.  Standard US practice does not use a special
character for this purpose, so the standard US locale ignores the aposrophe
in a format.   Other locales do provide one, however.

Here is an example of how you can use this in gnuplot:
Script:

A = 1234567.89 

set decimal locale 'en_US.UTF-8' 
US = sprintf("%'.2f", A) 
print "US format is ", US 

set decimal locale 'fr_FR.UTF-8' 
FR = sprintf("%'.2f", A) 
print "FR format is ", FR
Output:

decimal_sign in locale is . 
decimal_sign in locale is , 
US format is  1,234,567.89 
FR format is  1 234 567,89
