# LaTeX Fonts

## Description

Tecplot products include the ability to use your installed version of LaTeX Fonts to display complex formulae and equations directly on your plots. We test against MiKTeX and TeXLive, but should be compatible with other LaTeX engines.

Once you’ve installed a LaTeX tool, simply add a piece of text to the plot and click the “LaTeX” button to switch to LaTeX mode. Here you can enter simple items, like Greek letters such as phi, theta, and rho, to display LaTeX fonts.

You can even include complex equations like the Navier-Stokes equations.

We handle the sizing through familiar font size controls. All LaTeX text will default to black, but you can use LaTeX notation to specify colors, for example: \color{red}

This may require the addition of the xcolor package in the LaTeX configuration file, tecplot_latex.mcr. tecplot_latex.mcr is located in the base install directory and allows for customizations of how Tecplot 360 finds and uses LaTeX as well as which packages will be used. This file may also be placed in your home directory, if you don’t have write permissions at the installed location.

We’ve included some helpful examples in the documentation. Click the Help button in the Text Details dialog or search for “LaTeX” in the User’s Manual. Here’s the Documentation.
