在 Gnuplot 中引入带有特殊符号的框 [英] Introduce a box with special symbols in Gnuplot

问题描述

我想要一个 gnuplot，右上角有一个框，如下所示.我的难处是:

I want to have a gnuplot with a box on the right top corner like the one below. My difficulties are both:

1. 如何在图例中获取 \hat{Q}?
2. 如何添加包含标题的框?

推荐答案

set term cairolatex eps standalone size 3in,3in
set output 'Q.tex'
set key box opaque samplen 0.5
plot for [i=1:4] sinc(x)**i title sprintf('\tiny${\hat{Q}=%d}$',i) lw 2

standalone 关键字将输出包装在最少的 LaTeX 命令中，以便您可以直接运行 latex Q.如果您想生成 LaTeX 片段以包含在更大的文档中，请忽略此操作.

The standalone keyword wraps the output in minimal LaTeX commands so that you can run latex Q directly. Omit this if you want to produce a LaTeX fragment for including in a larger document.

我展示了如何构建一个包含 LaTeX 字体大小的格式化标题.请注意，格式使用单引号而不是双引号.

I show how to construct a formatted title that includes a LaTeX font size. Note that the format uses single quotes rather than double quotes.

此示例使用 cairolatex eps，因为您特别询问了 eps 文件.Normallay 我会使用 cairolatex png 或 cairolatex pdf 然后用 pdflatex 而不是普通的 latex 进行处理.

This example uses cairolatex eps because you specifically asked about an eps file. Normallay I would use cairolatex png or cairolatex pdf and process afterwards with pdflatex rather than plain latex.
