将字体样式定义为变量 [英] Define font style as a variable

问题描述

是否可以定义不同的字体样式(在gnuplot中)，以便以后可以通过索引引用它们，而不必每次都重复它们，例如: font1 =字体"Helvetica，12"； font2 =字体"Verdana，12"等等

Is it possible to define different font styles (in gnuplot), so that I can refer to them later by an index instead of repeating them all every time, for example: font1 = font "Helvetica,12" ; font2 = font "Verdana, 12" and so on

推荐答案

您可以为此使用宏.

set macros

启用此功能(默认情况下为版本5)，您可以定义字符串变量，这些字符串变量在执行命令之前将其内容替换为命令中的内容，例如

With this enabled (in version 5 by default), you can define string variables which are replaced in a command with their content before the command is executed, like

set macros
Helvetica = 'font "Helvetica, 12"'
Verdana = 'font " Verdana, 12"'

set title "My title" @Verdana
set xlabel "My x-label" @Helvetica
plot x
