Python数据分析与展示之matplolib库([matplotlib/matplotlib] Label subscript cutoff when increasing) 学习笔记手札及代码实战

Code for reproduction

import matplotlib.pyplot as plt
fig,ax = plt.subplots(dpi=300)
ax.set_ylabel(r"$\frac{E_0}{E_{\infty}}$",
              rotation=0,fontsize=30,labelpad=20)
plt.savefig("test.png")

Bug report

Bug summary

When using a (latex) fraction in the y axis the subscript is cutoff when the dpi and fontsize are increased. This behavior does not appear when using the default settings for figure dpi (100).

import matplotlib.pyplot as plt
fig,ax = plt.subplots(dpi=100)
ax.set_ylabel(r"$\frac{E_0}{E_{\infty}}$",
              rotation=0,fontsize=30,labelpad=20)
plt.savefig("test.png")
