How to do it...

The LaTeX string that we want to add is fairly simple, and it gives us a good taste of what the
syntax for this notation is:

1. We bind the LaTeX string to inv-log :

(def inv-log "f(x)=\\frac{1.0}{\\log x}")

2. We apply that to a chart using the incanter.latex/add-latex-subtitle

function:

(latex/add-latex-subtitle f-plot inv-log)

The chart relects the change immediately, as shown in the following screenshot:

Full information about LaTeX and its math notation is beyond the scope of this recipe.
The website for LaTeX is http://www.latex-project.org/ . The LaTeX wikibook has
a good chapter on typesetting mathematical equations, at http://en.wikibooks.org/
wiki/LaTeX/Mathematics , and The Not So Short Introduction to LaTeX 2ε ( http://
tobi.oetiker.ch/lshort/lshort.pdf ) is another good resource for learning LaTeX,
including the math syntax.
