Please help!! Folks I've been working on a placement exam which is due next week but I'm having trouble with some unwanted extra spacing that I get when using pstricks. I've searched but can't find any solutions to this prob.
Here's my latex code: [note that I don't use the extra space between $ signs; I use it here so it displays correctly.
$ $\begin{pspicture*}(-2,-1)(2,1) \psline[linewidth=1pt,linecolor=red]{<->}(-2,0)(2,0) \end{pspicture*}$ $
