matplotlib 标题中的乳胶和文本

2022-01-24 00:00:00 python matplotlib latex

问题描述

我正在尝试显示带有将普通文本与几个 Latex 命令组合在一起的标题的图像:

I'm trying to show an image with a title that combines normal text with a couple of Latex commands:

plt.imshow(w1subtracted2, origin='lower',
          extent=[l_max, -l_max, -b_max, b_max],
          cmap = color_map)
plt.title('W1 disk and central $pm2	extdegree$ subtracted', fontsize = 'small')
plt.xlabel(xlabel, fontsize = 'small')
plt.ylabel(ylabel, fontsize = 'small')
plt.savefig('w1subtracted2.png')

但我无法让标题显示 pm 和 extdegree 以乳胶样式显示.我怎样才能做到这一点?

but I can't get the title showing the pm and extdegree to show in Latex style. How can I achieve that?

解决方案

看来你使用的不是latex (usetex = True) 而是简单的MathText.MathText 中没有 extdegree.

It seems you are not using latex (usetex = True) but simple MathText. There is no extdegree in MathText.

使用

plt.title(r'W1 disk and central $pm2^circ$ subtracted', fontsize='small')

应该给你
