如何在 Matplotlib 中编写自己的 LaTeX 序言?

本文介绍了如何在 Matplotlib 中编写自己的 LaTeX 序言?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 中创建一个图形以插入到我的 LaTeX 文档中，我需要粗体 'i' 和'j' 符号不带圆点和帽子.

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.

我一直在我的文档中使用代码 mathbf{hat{ extnormal{fseriesi}}}，但是因为它使用了 amsmath包(或者可能是 amssymb 包，对不起，我不知道我对 LaTeX 和 matplotlib 都很陌生)我不能在matplotlib 标签.

I've been using the code mathbf{hat{ extnormal{fseriesi}}} 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包.我希望这是有道理的，我知道这可能已经存在或者很简单，但我是新手，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！

所以我以某种方式设法在编码方面做到了这一点，但是当我运行代码时，我的 python 内核 崩溃了.不幸的是，我并不真正理解我的代码或哪里出了问题，所以上传了它以防万一.抱歉上传时间长.再次提前感谢！

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!

from mpl_toolkits.mplot3d import Axes3D
import numpy, matplotlib, matplotlib.pyplot as pyplot

matplotlib.rcParams['text.usetex'] = True
matplotlib.rcParams['text.latex.preamble'] = [
    r'usepackage{amsmath}',
    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'$mathbf{hat{	extnormal{fseries i}}}$',
        fontsize=25, color = Module_Colour)
ax.text(0, 1.03, 0, r'$mathbf{hat{	extnormal{fseries j}}}$',
        fontsize=25, color = Module_Colour)
ax.text(0, 0, 1.03, r'$mathbf{hat{	extnormal{fseries k}}}$',
        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，不幸的是我不是很精通技术，所以很难理解为什么会发生这种情况.

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