如何使子图跨越 IEEEtrans 样式的两列？

Question

我有三个图，我想将它们并排放置以便进行比较，我使用的是 IEEEtrans。我找到了方程如何跨越两列的解决方案，但没有找到连续图的解决方案，任何想法、评论都将不胜感激，谢谢。

您可以使用星号figure*环境，无需任何[htpb]说明符。尽量让您的图形声明更靠近您想要放在旁边的文本。

如何影响 LaTeX 中图形和表格等浮动环境的位置？

\documentclass[final]{IEEEtran}%
\usepackage{subcaption}
\usepackage{kantlipsum} %<- For dummy text
\usepackage{mwe} %<- For dummy images

% Remove the trailing whitespace from citations
\usepackage[noadjust]{cite}

% Training subcaption package to comply with
% IEEE standards. We can ignore the warning
% generated by caption.sty which is due to 
% the redefinition of \@makecaption
\DeclareCaptionLabelSeparator{periodspace}{.\quad}
\captionsetup{font=footnotesize,labelsep=periodspace,singlelinecheck=false}
\captionsetup[sub]{font=footnotesize,singlelinecheck=true}
