How do I make it into a pie chart, combining NA and EU like this?

Thanks in advance
Firstly you should create a calculated dimension in master item tab with the expression below.
Region:
If(Region='AS','AS','NA/EU')
Then you take pie chart with this:
Dimension - Region (created above)
Expression - Count(Region)
