Math professor by day, hacker by night.

I teach calculus and try to implement teaching and new media technologies. I use a lot of LaTeX and the occasional scripting language.

So glad I found this site—now I can unsubscribe to some of those mailing lists I should be paying attention to but never have the time when the mails come.

comment Using remember picture with pgfplots
Seems to be a pgfplots bug that's been resolved. I reproduced the issue in pgfplots 1.6; when I updated to the TeXLive version (1.7) it went away.

That's the Mayer-Vietoris sequence. Couldn't have passed my qualifying exams without it!

There is a Mac utility called LaTeXit that comes with the MacTeX distribution.

What theme are you using? It would help if you could post a complete minimal working example (MWE).

To the question: couldn't multiple rows work just as easily?

comment Itemize inside longtable
@MarioS.E.: Most of us can't debug code by eyes alone. We have to copy and paste into a document, see what happens, poke it, see what happens, curse it, see what happens, etc. ... With an MWE we can get more quickly to the poking-and-cursing stage. Without it we have to manually type repetitive things like \documentclass...\begin{document}... and so on. Also we have to guess what packages are being loaded (especially annoying with multi-library packages like tikz and pgfplots), and it's a barrier to actually solving the problem. So MWE is always good if you want easy help. :-)

comment pgf plot, polar plot: how do i ensure that the 0 degree label begins in the north and not in the east?
Label placement is very customizable. Take a look at Section 4.14 of the pgfplots manual.
