Feb 6, 2015 at 20:34 comment added Hanmyo Thanks for the response. I think I'll post it as a separate question, as I'm looking to do something more complicated involving Abs.
Feb 6, 2015 at 13:27 comment added kglr @Hanmyo, i am getting the same "weird results" with Abs[#2]&. I don't know why; maybe a bug? Meanwhile, a work-around is to use ListLinePlot[data, MeshFunctions -> {#2 &}, Mesh -> {{-1, 1}}, MeshShading -> {Blue, Directive[Red, Dashed]}, MeshStyle -> None]. Btw, thank you for the accept.
Feb 6, 2015 at 8:45 comment added Hanmyo Thanks so much for the fast answer! Just a quick question about how to apply it. If I want to dash when the absolute value is greater than 1, this code produces weird results. Any idea? data = RandomReal[{-3, 3}, 100]; ListLinePlot[data, MeshFunctions -> {Abs[#2] &}, Mesh -> {{1}}, MeshShading -> {Blue, Directive[Red, Dashed]}, MeshStyle -> None]
