Graphing in Incanter - Clojure Data Analysis - page 284

How it works...
The incanter.charts/function-plot function takes the function to plot and the range
of the domain (from 0.0 to 1.0 in this case). We've added some labels to make things clearer,
but overall, this is a very straightforward function. Not having to worry about messy data
simpliies a lot of things!

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 topics 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 ile 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 :as latex])
We'll also use the chart that we made in Creating function plots with Incanter . We'll still use
the variable f-plot for it.
