I'm not sure what you mean by "little red dashes"...

If you mean "short red dashes" then it's style option 3 in the "set
line..." command:  http://cola.gmu.edu/grads/gadoc/gradcomdsetline.html

If you mean the red lines intersecting the main line as in your 2nd image
sample, I'm not aware of a GrADS command for such.  You could probably
create a function to do something similar as depicted in the
sample--perhaps another user has done this and will reply.
