Dynamic Reference Line by Dimension

[Anonymous]

I want a reference line that is dynamic based on the dimension selected in the chart. I am currently trying to use getObjectField() to do this but I can't get it to work. It looks like this:

=avg(total aggr(avg([Is In Arrears (MonthEnd)])
,$(= '[' & getobjectfield(0,'GnfAza') & ']')
,$(= '[' & getobjectfield(1,'GnfAza') & ']')
))

Can anyone help please?

Would you be able to share a sample where you have tried this? The syntax looks to be right.
