I have a single figure representing the system transitioning between 5 states proceeding from left to right. I would like to add an aligned sub-caption below each state (a), (b), etc. Because the states are all wrapped up in a single figure this exceeds my current understanding in Latex.
This is my code printing the figure:
\begin{figure*}[b!]
\centering
\includegraphics[width=\textwidth]{Figure_1.eps}
\caption{\label{fig:static_analysis} Transition graphs.}
\end{figure*}
For reference, this is what the SINGLE figure and caption end state should look like:
-- -- -- -- --
-- -> -- -> -- -> -- -> --
-- -- -- -- --
(a) (b) (c) (d) (e)
Fig. X: Transition states
Can I insert the sub-captions manually or do I need to split the figure up into individual chunks? The former would be preferred because of some transition arrows between the states.

figures; "[inserting] the sub-captions manually" and "[splitting] the figure up into individual chunks" are not that different. ;-) – L. F. Mar 19 '19 at 12:33
