Re: GMT5 How to draw a double-headed straight line?

You just add +b (for head at beginning) and +e for head at end.  From psxy:

	     +b to place a vector head at the beginning of the vector [none].
	     +e to place a vector head at the end of the vector [none].

So something like -Sv0.25i+b+e and use -G for head color and -W for line.

-p
