如何在Matplotlib中编写自己的LaTeX前言?

本文介绍了如何在Matplotlib中编写自己的LaTeX前言?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试在matplotlib中创建一个要插入我的LaTeX文档中的图形，并且我需要粗体的'i'和'j'符号而不是它们的点和帽子.

I'm trying to create a figure in matplotlib to insert in my LaTeX document, and I need the bold 'i' and 'j' symbols without their dots and a hat instead.

我一直在文档中使用代码\mathbf{\hat{\textnormal{\bfseries\i}}}，但是由于它使用了amsmath包(或者可能是amssymb包，对不起，我不知道我对这两个LaTeX都是陌生的和matplotlib)我不能在matplotlib标签中使用它.

I've been using the code \mathbf{\hat{\textnormal{\bfseries\i}}} in my document, but as this uses the amsmath package (or possibly the amssymb package, sorry I don't know I am very new to both LaTeX and matplotlib) I cannot use it in the matplotlib label.

因此，我很想知道如何在matplotlib中使用LaTeX，以及如何编写序言来安装使用这些符号所需的软件包.我希望这是有道理的，而且我知道这可能已经存在或很简单，但是我是新手，所以请不要生气！

Hence I would love to know how to use LaTeX in matplotlib and how to write a preamble to install the package needed to use these symbols. I hope this makes sense, and I know this is probably already out there or is simple but I'm new so please dont get angry!

谢谢你们！

所以我已经设法通过编码使这一步走到了尽头，但是无论何时我运行代码，我的python kernel都会崩溃.不幸的是，我不太了解我的代码或它出了什么问题，因此请上载以防万一.抱歉，长时间上传.再次感谢！

So I have somehow managed to get this far with the coding, but when ever I run the code, my python kernel crashes. Unfortunately I don't really understand my code or where it is going wrong, so have uploaded it in case it helps. Sorry for the long upload. Again thanks in advance!

    r'\usepackage{amssymb}']
matplotlib.rcParams['font.family'] = 'serif'
matplotlib.rcParams['font.serif'] = 'Computer Modern'
matplotlib.verbose.level = 'debug-annoying'

Module_Colour = '#F0AE1E'

fig = pyplot.figure()
ax = fig.add_subplot(111, projection='3d')

X_arr = numpy.array([1.0,0.0,0.0])
Y_arr = numpy.array([0.0,1.0,0.0])
Z_arr = numpy.array([0.0,0.0,1.0])
O_arr = numpy.array([0.0,0.0,0.0])

pyplot.quiver(O_arr,O_arr,O_arr,X_arr,Y_arr,Z_arr,
              pivot='tail', length=1.0, linewidth=2.5,
              color = Module_Colour)

ax.set_xlabel('x-axis', fontsize=12.5)
ax.set_ylabel('y-axis', fontsize=12.5)
ax.set_zlabel('z-axis', fontsize=12.5)

ax.text(1.03, 0, 0, r'$\mathbf{\hat{\textnormal{\bfseries \i}}}$',
        fontsize=25, color = Module_Colour)
ax.text(0, 1.03, 0, r'$\mathbf{\hat{\textnormal{\bfseries \j}}}$',
        fontsize=25, color = Module_Colour)
ax.text(0, 0, 1.03, r'$\mathbf{\hat{\textnormal{\bfseries k}}}$',
        fontsize=25, color = Module_Colour)

ax.set_xlim3d([0, 1.05])
ax.set_ylim3d([0, 1.05])
ax.set_zlim3d([0, 1.13])
ax.view_init(elev=17.0, azim=44.0)

pyplot.savefig('file/pathway/figure.jpeg',
               bbox_inches='tight')
pyplot.show()

然后python.exe停止响应，很遗憾，我对技术的了解不是很深，所以很难理解为什么会这样.

Then python.exe stops responding, and unfortunately I'm not very tech savvy so struggle to understand why this is happening.

推荐答案

当我需要将LaTeX与matplotlib结合使用时，我将以下内容添加到python脚本中(+其他用于调试信息的命令)

When I need to use LaTeX with matplotlib, I add the following to the python script (+ additional commands for debug info)

 import matplotlib.pyplot as plt

 plt.rc('text', usetex=True)
 plt.rc('text.latex', preamble=r'\usepackage{amsmath}
          \usepackage{foo-name} `...')
 matplotlib.verbose.level = 'debug-annoying'

在此处进行绘制的命令
