Incanter charts can be saved as PNG files using the save function, but I had a request earlier today to add the ability to save them as PDF documents.

So I’ve created a new function called save-pdf in a new package called incanter.pdf .

Here’s a basic example.

(use '(incanter core charts pdf)) (save-pdf (function-plot sin -4 4) "./pdf-chart.pdf")

Which outputs the following PDF file.
