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 pgfplots ybar intervals on the left instead of on the right
I'm not sure what you mean by that. I do want the diagram to look like the second graphic.

comment Using includegraphics makes pdf very large
Is the PDF a static file or is going to change a lot? Because you could split the 30-page PDF into individual files with pdftk burst and just include the pages you want.

comment Formatting the union of sets
“irremediably” seems a bit harsh; after all, you can change the limits to super/subscripts and it's all better. :-)

comment How to make a short running author list?
@MartinWang: In many journals if two of three authors share an address the address is listed twice.

comment Pgfplots: picture moves with sample size!
For variable tick locations, you can use \pgfmathsetmacro{\tickone}{1-\DELTA/2}\pgfmathsetmacro{\ticktwo}{1+\DELTA/2} then xtick={0,\tickone,\ticktwo,2}.

comment Pgfplots: picture moves with sample size!
You have more than one question here (all of them good). Better to ask them separately.

comment Separating the preamble to another file
@TimHoffmann: either are perfectly acceptable. But if you are putting auxiliary code in a package you will probably want to use it more than once. That suggests a central location.
