Text objects in plots (like titles, labels, texts...) in the OpenGL renderer only support plain text and TeX. The latter consists of a very limited subset of the TeX language. On the other hand, the LaTeX formatting support is expected to provide full LaTeX capabilities.

The matplotlib project [http://matplotlib.sourceforge.net/users/usetex.html has already done this in Python] and might be used as an example of how to do this in Octave. There is also [https://github.com/jkriege2/JKQtPlotter JKQtPlotter], a Qt based plotting application which implements its own LaTeX parser/renderer in C++. | * Implement our own LaTeX parser and renderer.
