当我使用 matplotlib 或 Seaborn 生成（线）图并使用 tikzplotlib 保存以便稍后在 latex 中使用时，出现错误。在我向图中添加图例之前，一切正常。
这完全阻碍了整个文档的编译。有人能帮我吗？
以下是我在 Python 中生成表格的方法：
sns.lineplot(data = all_ar[["AAR_full", "AAR_n_blob", "AAR_p_blob", "AAR_n_flair", "AAR_p_flair", "AAR_n_vader", "AAR_p_vader"]])
plt.ylabel("Abnormal return (%)")
plt.legend(["full", "n_blob", "p_blob", "n_flair", "p_flair", "n_vader", "p_vader"], bbox_to_anchor=(1.02, 0.55), loc='upper left', borderaxespad=0)
tikzplotlib.save(
r"/Users/.../src/figures/ave_stock.tex")
代码在 Latex 中的样子如下：

我还注意到几年前也有人问过同样的问题，但是解决方案不起作用：使用 tikzplotlib 保存的带有图例的绘图在乳胶中产生错误
答案1
您尝试向图例添加包含下划线 ( _) 的字符串，下划线会导致 TeX 认为以下内容是必须处于数学模式的下标，从而导致错误。
您可能希望使用反斜杠来转义这些下划线，例如\_：
