I'm having some trouble creating a graph of the f(x) = tan x in
pstricks. I'm trying to use \psplot. First of all, I can't end a cycle
at -pi and pi, because of the asymptotic conditions at the endpoints.
Also, anything that crosses the asymptote makes a vertical line over
the whole page. Is there a way to limit the vertical range of a graph
and just have it put arrows on the end or something? Sorry if this is a
newbie-ish question, but I've never used LaTeX or pstricks before.
