I have 3 figures to be put in a figure which spans over a single column in a two-column document. The first two subfigures are similar and should be grouped together with labeling a(i) and a(ii) and the third subfigure should have a label of (b). I am using \subfigure command as follows. Is there a way to arrange the first two figures within one more subfigure and the third one in a separate subfigure? Currently I am getting the labels as (a) , (b) and (c) Something like this:

enter image description here


\begin{figure*}[] % not h only


\caption{Overall title }

  • Please make your code compilable by adding the documentclass as well as the required packages. Which package do you currently use to number your subfigures: subfig, subcaption or subfigure? From the code you uncluded, I assume you use the latter. If that's correct, please keep in mind that subfigureis deprecated. Please switch to subfig or subcaption instead.

Here is my suggestion using the subcaption package:

enter image description here

\usepackage[demo]{graphicx} % do not use the demo option in actual document

      \renewcommand\thesubfigure{\alph{subfigure} (i)}
      \renewcommand\thesubfigure{\alph{subfigure} (ii)}
  \caption{overall caption for all three subfigures}
