| """ | |
| Configures Matplotlib so saved figures can be used in LaTeX documents. | |
| Uses the sans-serif TeX Gyre Heros font (Helvetica), also for math. | |
| Arguments: | |
| - document_fontsize: Font size in points (use "\the\fontdimen6\font" in | |
| your LaTeX document to get the current value). The default is for a | |
| LaTeX Beamer document at 14pt ("\documentclass[14pt]{beamer}") which | |
| for some reason is slightly more than 14pt. | |
| - available_width: The available width in your LaTeX document, usually | |
| the value of "\textwidth". The default is for a LaTeX Beamer document | |
| with the default theme. | |
| Returns a function that calculates figure size given a fraction of the | |
| available width for the figure to occupy. | |
| Figures can be saved as PDF: | |
| fig.tight_layout(pad=0.1) | |
| fig.savefig('figure.pdf') | |
| And included in your document as follows: | |
| \begin{frame} | |
| \begin{center} | |
| \includegraphics[width=1.0\textwidth,transparent]{figure.pdf} | |
| \end{center} | |
| \end{frame} | |
| Todo: | |
| - Make font family and face configurable. | |
| - Example IPython Notebook and LaTeX document. | |
| - Document dependencies (tex-gyre, dvipng, ...). | |
