轴标签中的希腊字母不起作用 [英] Greek letters in axes labels are not working

问题描述

我正在尝试在情节的xlabel中使用希腊字母.互联网上的每个解决方案都说Matlab将接受tex.但是，我的x轴不是德尔塔符号，而是简单地标记为'D'

I'm trying to use Greek letters in my xlabel of a plot. Every solution on the internet says that Matlab will accept tex. But instead of the delta-symbol my x-axis is simply labeled 'D'

a = plot(0:40, y);
hold on

plot(delta_T,brechkraft, 'x')
errorbar(delta_T, brechkraft,delta_b,'x');

title('2mm Oelschicht');


xlabel('\Delta');
ylabel('Brechkraft D in 1/cm');
annotation('textbox', [.2 .8 .1 .1],...
    'String', {'Fit: f(x) = m*x + b',    ['m = ', num2str(p(1)) ],    ['b = ', num2str(p(2)) ]});
shg
hold off

saveas(a, 'abc1.png','png');

推荐答案

有点好奇，您的语法似乎还不错.您是否搞砸了系统的某些字体?或者，您的'interpreter'设置为none(文档文字道具)?

It's a little curious, your syntax seems alright. Have you screwed up some fonts of your system? Or maybe your 'interpreter' is set to none (doc text props)?

用(hx = xlabel的句柄)进行检查:

Check it with (hx = handle of xlabel):

get(hx, 'Interpreter')

并设置为:

set(hx, 'Interpreter', 'tex')

如果这不起作用，作为第一种解决方法，您可以尝试激活 Latex解释器，而不是通常的默认tex.

If that is not working, as a first workaround you could try to activate the Latex interpreter instead of the usually default tex.

x = 0:40;
y = x.^2;

plot(y,x, 'x')
title('\alpha \beta \gamma');

hx = xlabel('Symbol $\sqrt{\Delta}$  ','interpreter','latex');
hy = ylabel('Symbol $\sqrt{\epsilon}$','interpreter','latex');

但是实际上对于简单的希腊字母来说，这是没有必要的！

使用默认的tex解释器:

hx = xlabel('\Delta');
hy = ylabel('\epsilon');

也在工作:

但无法与乳胶语法delta一起使用:

but used with latex syntax delta is not recognized anymore:

xlabel('Symbol $\sqrt{\Delta}$  ','interpreter','tex');
ylabel('Symbol $\sqrt{\epsilon}$','interpreter','tex');

其他想法:

当您键入get(0,'DefaultAxesFontName')时，它将返回什么字体? 将其设置为 Helvetica 或 Arial 时可以使用吗?

What font does it return when you type: get(0,'DefaultAxesFontName')? Does it work when you set it to Helvetica or Arial?

set(0,'DefaultAxesFontName','Helvetica');

据报道，在某些系统(例如 Ubuntu 12.xx)上，您需要先安装 tex字体.

It is also reported that on some systems (e.g. Ubuntu 12.xx) you need to install tex fonts first.
