When you turn on Scatter Chart-[Properties]-[Presentation]-[Pop-up Labels],
the labels for dimensions and expressions will be displayed as follows
<Example>
----------------------------
Dimension1 = aaa
Dimension 2 = bbb
Expression 1 = ccc
Expression 2 = ddd
----------------------------
So if we set the same fields for the dimension and expression,
duplicate values will be displayed.
It would be great if we could select the range that pops up
(e.g. only dimensions, only expressions) so that we can eliminate duplicates
and users can see unique label.
