Adding equations to Incanter charts

We've seen how to add a title to the charts and labels on the axes, but so far, they've all used only plain, unformatted text. Sometimes, we might want to use a formula instead.

Incanter lets you add a formula to a chart using LaTeX's mathematical notation. LaTeX (http://www.latex-project.org/) is a professional grade document typesetting system. We won't go into the details of its math notation—there are plenty of books and tutorials out there already. Instead, we'll just see how to use it with Incanter.

In this recipe, we'll take the chart from the last recipe, Creating function plots with Incanter, and add the function as a subtitle.

Getting ready

We'll use the same dependencies in our project.clj file as we did in Creating scatter plots with Incanter.

We'll use this set of imports in our script or REPL:

(require '[incanter.core :as i]
         '[incanter.charts :as c]
         '[incanter.latex...
