Override Stacked Bar Chart Legend

Good morning,

I had a bar chart showing the expecting invoicing over the next 11 months.  I wanted to be able to see how much I have billed towards the goal so I created a field on my invoices table which is a checkbox and it is a formula checkbox.  If it sees an invoice # it marks the field true meaning that it was invoiced to the client.  GREAT, works fine.

I use this on my stacked bar chart and it works great.

Except the data label of yes/no will not make sense to an end user.  Is there a way to override that?  If not I think I need to switch the checkbox formula field to a text formula field and use that to create better labels.  Just wasnt sure if I can override it in the report settings somewhere.

Thanks!​
