pandoc-plot

A Pandoc filter to generate figures from code blocks in documents

pandoc-plot turns code blocks present in your documents (Markdown, LaTeX, etc.) into embedded figures, using your plotting toolkit of choice, including Matplotlib, ggplot2, MATLAB, Mathematica, and more.

Overview

This program is a Pandoc filter. It can therefore be used in the middle of conversion from input format to output format, replacing code blocks with figures.

The filter recognizes code blocks with classes that match plotting toolkits. For example, using the matplotlib toolkit:

# My document

This is a paragraph.

```{.matplotlib}
import matplotlib.pyplot as plt

plt.figure()
plt.plot([0,1,2,3,4], [1,2,3,4,5])
plt.title('This is an example figure')
```

Putting the above in input.md, we can then generate the plot and embed it in an HTML page:

pandoc --filter pandoc-plot input.md --output output.html

The resulting output.html looks like this:

<h1 id="my-document">My document</h1>

<p>This is a paragraph.</p>

<figure>
<img src="plots\9671478262050082276.png" />
</figure>

Supported toolkits

pandoc-plot currently supports the following plotting toolkits (installed separately):

• matplotlib: plots using the matplotlib Python library;
• plotly_python : plots using the plotly Python library;
• plotly_r: plots using the plotly R library
• matlabplot: plots using MATLAB;
• mathplot : plots using Mathematica;
• octaveplot: plots using GNU Octave;
• ggplot2: plots using ggplot2;
• gnuplot: plots using gnuplot;
• graphviz: graphs using Graphviz;
• bokeh: plots using the Bokeh visualization library;
• plotsjl: plots using the Julia Plots.jl package;
• plantuml: diagrams using the PlantUML software suite;
• sageplot: plots using the Sage software system;
• d2: plots using D2;
• asymptote: plots using Asymptote.

To know which toolkits are useable on your machine (and which ones are not available), you can check with the toolkits command:
