[Paraview] only displaying a range of line attribute values

[Tanaka Simon]

easy question, but somehow i failed to google it.

i have (4.2.0):
- multiblock .vtm data
- applied "ExtractBlock" filter to get the block containing some lines
- the lines have a scalar attribute

now i want to only display those lines which have attribute==1, for example.

what filter do i have to apply?

thanks
