matplotllib图形大小和xelatex之间的长度比例不匹配

Question

我创建了一个 pythonmatplotlib图形import matplotlib.pyplot as pltxwidth = 418.25555 / 72 # conversion from in to ptywidth = 300 / 72 # conversion from in to ptfig,ax = plt.subplots(figsize=[xwidth, ywidth])ax.plot([1,2,3],[1,2,3])ax.set_ylabel("Y-label")ax.set_xlabel("X-label")fig.savefig("test.pgf", bbox_inches="tight", pad=0)我在 XeLaTeX 中确定了xwidth通孔\the\textwidth，并且必须将其转换为英寸。一英寸定义为 72 磅。但是，如果我将图形包含到文档中，它与线宽不匹配：\documentclass{scrartcl}\usepackage{pgf}\begin{document}  \begin{figure}    \input{test.pgf}  \end{figure}  Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam\newline  Linewidth: \the\textwidth\end{document}结果如下：我究竟做错了什么？

Answer 1

我认为，当您使用 时bbox_inches="tight"，您会缩短图形以删除空白，并且不会延长轴。

对我来说使用constrained_layout = true或plt.tight_layout()在乳胶下工作。

import matplotlib.pyplot as plt

xwidth = 418.25555 / 72 # conversion from in to pt

ywidth = 300 / 72 # conversion from in to pt

fig,ax = plt.subplots(figsize=[xwidth, ywidth], constrained_layout = True)

ax.plot([1,2,3],[1,2,3])

ax.set_ylabel("Y-label")

ax.set_xlabel("X-label")

fig.savefig("test.pdf")

或者

import matplotlib.pyplot as plt

xwidth = 418.25555 / 72 # conversion from in to pt

ywidth = 300 / 72 # conversion from in to pt

fig,ax = plt.subplots(figsize=[xwidth, ywidth])

ax.plot([1,2,3],[1,2,3])

ax.set_ylabel("Y-label")

ax.set_xlabel("X-label")

plt.tight_layout()

fig.savefig("test.pdf")
