我目前正试图用斜体字来制作xlabel。
我先做了什么把终端设置为postscript。（我已经检查过它是否包含在我使用“set terminal”命令安装的gnuplot中）
gnuplot> set terminal
Available terminal types:
canvas HTML Canvas object
cgm Computer Graphics Metafile
context ConTeXt with MetaFun (for PDF documents)
corel EPS format for CorelDRAW
dumb ascii art for anything that prints text
dxf dxf-file for AutoCad (default size 120x80)
eepic EEPIC -- extended LaTeX picture environment
emf Enhanced Metafile format
emtex LaTeX picture environment with emTeX specials
epslatex LaTeX picture environment using graphicx package
fig FIG graphics language for XFIG graphics editor
gif GIF images using libgd and TrueType fonts
hpgl HP7475 and relatives [number of pens] [eject]
jpeg JPEG images using libgd and TrueType fonts
latex LaTeX picture environment
lua Lua generic terminal driver
mf Metafont plotting standard
mp MetaPost plotting standard
pcl5 HP Designjet 750C, HP Laserjet III/IV, etc. (many options)
png PNG images using libgd and TrueType fonts
postscript PostScript graphics, including EPSF embedded files (*.eps)
gnuplot> set terminal postscript Terminal type set to 'postscript' Options are 'landscape enhanced defaultplex \ leveldefault monochrome colortext \ dashlength 1.0 linewidth 1.0 butt noclip \ nobackground \ palfuncparam 2000,0.003 \ "Helvetica" 14 fontscale 1.0 '
将终端设置为postscript后，我执行了以下操作： -
gnuplot> set termoption enhanced
gnuplot> set xlabel "{/Times-Italic italics}"
然后当我尝试绘制图表时发生这种情况，但没有图形输出。当我使用终端q时，有一个图形输出，但我想使用postscript终端，因为我希望我的标签是斜体。

我不确定是什么问题，所以我只是复制并粘贴整个终端输出。对不起，这太久了..
答案 0 :(得分：1)
你问过postscript，它给了你PostScript。像这样的终端只是以适当的格式写出输出，并且gnuplot不应该给出一个图形窗口来显示它的外观。
您可以通过添加行
将PostScript写入文件set output "output.ps"
output.ps。
不生成图形窗口对批处理作业或脚本编写很有用。例如，在撰写论文时，我通常会编写一个构建脚本来调用gnuplot来构建我的图形.eps（或.pdf）---通常是很多文件。然后在我的LaTeX文件中使用它们。如果您有许多绘图或重要依赖项，这将特别有用。我运行一个脚本，它根据需要构建所有内容。这种编写脚本的能力是gnuplot非常有用的一个原因。
您可能需要考虑使用＆＃34;封装的PostScript＆＃34; （.eps）带有终端选项eps。 EPS与postscript的输出相同，但周围有一个边界框（它也有不同的文件头，但格式相同）。您想要的取决于您使用PostScript的任何内容。您还可以将终端选项放在与set terminal：
set terminal postscript eps enhanced
