Why can't I run the following command in my TeXShop?
\documentclass{article}
\usepackage{pstricks-add}
\begin{document}
\psset{algebraic=true}
\pspicture(-2,-0.5)(2,2)
\psline{<->}(-2,0)(2,0)
\psline{->}(0,-0.5)(0,2)
\psplot{-1.5}{1}{x*x+x}
\endpspicture
\end{document}
Best Answer
In TeXShop, you can choose the TeX and DVI item from the Typeset menu, and then compile your document. Alternatively, (and a better solution) you can put the following line in your file:
as the first line of your document. (This line can be generated by TeXShop by choosing the Program item from the Macros menu, and choosing
latex
from the list provided by the macro.)
