I want to produce a plot like this:

ROOT
1

http://www.usatlas.bnl.gov/~ketevi/html/charged_higgs_l300_contour.eps

I assume it has been produced with root, but I have no idea how to do these lines with the (almost) vertical small lines pointing into one direction… does anybody know how to do it?

Thanks, Martin
