Concat Set Analysis and Text in Qlik Sense Chart

[ZoeM]

Hello!

I have chart (below) which is showing the date based on a Set Analysis expression (also below).

I am unable to show/display the Measures title in the chart, so I want to force the title in by concatenating the expression and the text for the label, but I am getting an error with the concat expression.

Expression:

=Date(Only({$<[Date Type]={'Build Dates'},Gateways={'ABC'}>}[Date]),'DD-MMM-YY')

Measure Title: 'ABC'

Thank you!
