[gradsusr] remark line in grads

[Jeff Duda]

Chinh,
Use the draw string, draw mark, draw line, and draw rec or draw recf
commands.  You need to supply those commands with x and y coordinates of
the endpoints of the line, a reference point for the string, or corners of
the box.  You can obtain those either by entering q pos and clicking on the
screen where you want to get coordinates, then saving the output that comes
from that, or by using q w2xy a b, where a and b are the phase coordinates
(in your case, time and temperature are the coordinates), and saving the
output from that.
