gnuplot 中的 epslatex 没有给出正确的输出 [英] epslatex in gnuplot does not give right output

问题描述

我正在使用以下脚本来生成一个简单的 eps 图片:

I am using the following script to generate a simple eps image:

set terminal epslatex 8
set output 'sample1.tex'
set size 0.75,0.75
set xrange [-pi:pi]
set yrange [0:1.2]
set xlabel "$x$"
set ylabel "$y$"
plot sin(x)*sin(x) title "$\sin^2(x)$"

但是，当我在 gnuplot 中运行它时

However, when I run it in gnuplot

gnuplot> load "sample.gpi"

我得到一个空白图像，只显示没有数字的网格.有什么建议我做错了吗?

I got a blank image, just the grids without numbers are shown. Any suggestion what I'm doing wrong?

推荐答案

您可能正在查看 sample1-inc.eps 文件.但是您必须先编译输出 LaTeX 文件.为此，使用 standalone 选项并从脚本本身编译非常方便:

You are probably viewing the sample1-inc.eps file. But you must compile the output LaTeX-file first. For this it is very convenient to use the standalone option and compile from within the script itself:

set terminal epslatex 8 standalone
set output 'sample1.tex'
set size 0.75,0.75
set xrange [-pi:pi]
set yrange [0:1.2]
set xlabel "$x$"
set ylabel "$y$"
plot sin(x)*sin(x) title "$\sin^2(x)$"

set output # finish the current output file
system('latex sample1.tex && dvips sample1.dvi && ps2pdf sample1.ps')

现在您可以load 'sample1.gpi' 并以sample1.ps 或sample1.pdf 形式查看完整的输出.如果您在 Windows 上，您可能需要使用三个单独的 system 调用进行编译(只是猜测):

Now you can load 'sample1.gpi' and view the complete output as sample1.ps or sample1.pdf. If you are on Windows you may need to compile with three separate system calls (just guessing):

system('latex sample1.tex')
system('dvips sample1.dvi')
system('ps2pdf sample1.ps')
