I'm using the subcaption
package to make some subfigures with subcaptions (clearly), in a two column document, specifically the IEEE Transactions journal document class.
There are a lot of figures, but some typical code for one of them is:
\begin{figure}
\centering
\begin{subfigure}[b]{0.3\textwidth}
\includegraphics[height=65mm,clip=false]{figures/test_preds/s5_test_preds.pdf}
\caption{Session 5 test data}
\end{subfigure}
~
\begin{subfigure}[b]{0.3\textwidth}
\includegraphics[height=65mm,clip=false]{figures/test_preds/s32_test_preds.pdf}
\caption{Session 32 test data}
\end{subfigure}
\caption{Label predictions using cross-correlation-, GTW-, and LSTM-based classifiers}
\end{figure}
Which produces the example on the left.
So not only do the images end up skewed to the right of the current column despite the \centering
, but the subcaption is prematurely given a line break. The figure on the right has the same centering issue.
I should also mention that I'm only including \usepackage{subcaption}
, as subcaption
seems to subsume subfigure – Latex tells me I'm multiply defining subfigure if I \usepackage
that as well.
Due to lack of time I'm tempted to solve this using \hspace
(urgh), but it wouldn't solve the premature line-breaking of the subcaptions.

You have defined your
subfigure
environments to have a width of.3\textwidth
, but your images are wider than that, so they will stick out on the right side. This is also the reason the captions are narrow, as they have the same width as thesubfigure
s. So to fix this, just increase the width. You can use\columnwidth
to make them as wide as the columns.See the below code for an example, where I also added an
\fbox
around the eachsubfigure
, so their boundaries are obvious.
