如何在gnuplot中包含希腊字母? [英] How do I include greek letter in gnuplot?

问题描述

我正在使用ubuntu 14.04和gnuplot-x11，发现对于希腊字母alpha，

I'm using ubuntu 14.04 and gnuplot-x11, and found that for greek letter alpha,

{/symbol a}可以工作，但这只是向我显示{/symbol a}，而不是希腊字母alpha.

{/symbol a} will work, but that just shows me {/symbol a}, not greek letter alpha.

我尝试了{\ symbol a}或其他选项，但这不起作用.

I tried {\symbol a} or other options, but that does not work..

推荐答案

使用语法{/Symbol a}要求您启用enhanced模式.这可以通过几种方式完成:

Using the syntax {/Symbol a} requires that you enable the enhanced mode. This can be done in several ways:

1. 设置终端时

1. When setting the terminal

set terminal ... enhanced

将终端设置为

After setting the terminal with

set termoption enhanced

明确表示单个标签

Explicitely for a single label

set xlabel '{/Symbol a}' enhanced

根据您使用的输出终端，最好的选择是使用utf-8编码并直接输入字符:

Depending on the output terminal you are using, the best option is to use utf-8 encoding and directly input the characters:

set encoding utf8
set xlabel 'α'
