how to add tex to octave graph

问题

I have a bar graph, and I am using text() to display fractions above each of the bars. For example:

text(1, 20, "300/400")

displays the string "300/400" at position (1,20).

I would now like to prettify the fractions so that "300" appears over the "400":

300
---
400

Is there a way to do this, eg with tex or latex?

I tried each of these, but the interpreter is not getting called:

text(1, 20, '\frac{300}{400}');
text(1, 20, '\frac{300}{400}', 'interpreter', 'tex');
text(1, 20, '\frac{300}{400}', 'interpreter', 'latex');

回答1:

It looks like it's not yet possible in Octave. The TeX interpreter doesn't support the \frac structure, and the LaTeX interpreter isn't yet implemented.
