Bug summary
When using Matplotlib to generate PGF files with theIEEEtran document class, I noticed that if the legend font size is smaller than 5, extra whitespace appears on the right side. Currently, my workaround is to forcibly override the defaultarticle document class, which avoids this issue.
Would it be possible to provide an interface allowing users to directly modify the documentclass used by Matplotlib? Below is the reproducible code and a screenshot demonstrating the issue.
\documentclass{IEEEtran}\usepackage{pgf}\begin{document}\input{main.pgf}\end{document}
Overriding the default definition can resolve this issue.
