如何将tex添加到八度图 [英] how to add tex to octave graph

问题描述

我有一个条形图，并且我正在使用text()在每个条形上方显示分数.例如:

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")

在位置(1,20)显示字符串"300/400".

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

我现在想美化分数，以使"300"出现在"em"上方，而不是"400"之上:

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

300
---
400

有没有办法做到这一点，例如使用tex或乳胶?

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

我尝试了所有这些方法，但是没有调用解释器:

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');

推荐答案

在Octave中似乎还不可能. TeX解释器不支持\ frac结构，并且LaTeX解释器尚未实现.

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.
