Create a new line in dimension field created as an expression

[Anonymous]

All,

Is it possible to create a new line in pie chart dimension field created as an expression?

Eg:

something like this

=IF (LEN(field1) >0, field1&', '& chr(10) & chr(13) & aggr(COUNT(([key1])),[field1]))

Current Result value for Pie Chart Dimension:

abc, xyz

Expected Result value for Pie Chart Dimension:

abc,

xyz

Please share your knowledge. Thank you
