Check if a selection is defined

[#1]

Hello.

How can I check if a selection of any type is defined in my document? I need it to show or not a graph line.
I've tried working with GetCurrentSelections() but I can't handle the '-' result. It doesn't seems to be a null(), neither a '-' of course.

Thank you!

Hello Luca,

If your document has no selections at all,

Len(GetCurrentSelections()) = 0

otherwise, length of current selections will vary, and will be always greater than 0. Hope that helps!

Thank you Miguel!

Solution was just a step ahead, as usual... I was looking for a length() function and of course thre's one: len()! Cheers!
