# Changing the enumeration of the sub-figures

I am working on my thesis. There is this rule for the enumeration of the sub-figures:

Sub-figures should be enumerated by adding the corresponding lowercase letter to the Figure designation such as Figure 3.8a

However, I could only manage the 3.8(a)

The code that I am using this:

\begin{figure}[h]
\subfigure[]{\includegraphics[width=\textwidth]{2016.png}
\label{2016}}
\subfigure[]{\includegraphics[width=\textwidth]{2017.png}
\label{2017}}
\caption{Graphs of daily averages of Turkish hourly electricity consumption values in \subref{2016} 2016
\subref{2017} 2017.}
\label{consumptions}
\end{figure}


The thesis rules tell us to use subfigure package. How can I get 3.8a instead of 3.8(a)? Thank you!

As pointed by @Zarko in the comments, subfigure is deprecated and is now covered by subfig or subcaption.

To achieve what you want with subcaption we'll change the default setup by adding :

\usepackage[labelformat=simple]{subcaption} %%default is [labelformat=parens]

%%Setup for captions
%%If you want figure numbering as 'figure 3.8'
\renewcommand{\thefigure}{\thechapter.\arabic{figure}}
%%if you want 3.8a for subfigure
\renewcommand{\thesubfigure}{\normalsize\thefigure.\alph{subfigure}:}
%%if you want figure 3.8a for subfigure
\renewcommand{\thesubfigure}{\normalsize figure \thefigure.\alph{subfigure}:}


Here is a complete testing code :

\documentclass[10pt,a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}

\usepackage{caption}

\usepackage[labelformat=simple]{subcaption} %%default is [labelformat=parens]
%%If you want figure numbering as 'figure 3.8'
\renewcommand{\thefigure}{\thechapter.\arabic{figure}}
%%if you want 3.8a
%\renewcommand{\thesubfigure}{\normalsize\thefigure.\alph{subfigure}:}
%%if you want figure 3.8a
\renewcommand{\thesubfigure}{\normalsize figure \thefigure.\alph{subfigure}:}

\begin{document}
\chapter{fist chapter}
\begin{figure}

\begin{subfigure}{0.45\linewidth}

\end{subfigure}\hfill
\begin{subfigure}{0.45\linewidth}
