Latex Chart Title style setting __ All kinds of Office software installation and Environment configuration

To set the icon heading style you need to import \caption and \subcaption package, you can change the caption and label font, encoding style, alignment, format, etc. Insert a child graph

The code is as follows

\begin{figure}	
	\centering
	\begin{subfigure}[t]{1in}
		\centering
		\includegraphics[width=1in]{ PLACEHOLDER}
		\caption{caption 1}\label{fig:1a}		
	\end{subfigure}
	\quad
	\begin{subfigure}[t]{1in}
		\centering
		\includegraphics[width=1in]{placeholder}
		\caption{caption 2}\label{fig:1b}
	\end{ Subfigure}
	\caption{main figure caption}\label{fig:1}
\end{figure}

Insert child table

Code Similar

\begin{table}	
	\centering
	\begin{subtable}[t]{2in}
		\centering
		\begin{tabular}{|l|l|l|}
		\hline
		& & 300\\
		\hline
		& & 600\\
		\hline
		\end{tabular}
		\ Caption{caption 1}\label{table:1a}
	\end{subtable}
	\quad
	\begin{subtable}[t]{2in}
		\centering
		\begin{tabular}{|l|l|l|}
		\hline
		& & 300\\
		\hline
		& & 600\\
		\hline
		\end{tabular}
		\ Caption{caption 2}\label{table:1b}
	\end{subtable}
	\caption{main table caption}\label{table:1}
\end {table}

You can use \columnwidth instead of \width to set the caption numbering style

% change the style of the caption numbering.
\renewcommand{\thetable}{\alph{table}}
\renewcommand{\thefigure}{\alph{table}}
\renewcommand{\ Thesubtable}{\roman{subtable}}
\renewcommand{\thesubfigure}{\arabic{subfigure}}

Counter Style	Code	Example
Arabic numerals	\arabic{counter}	1, 2
Lower Case Letters	\alph{counter}	A, b
Upper Case Letters	\alph{counter}	A, B
Lower Case Roman	Numerals \roman{counter}	I, II
Upper Case Roman	Numerals \roman{counter}	I, II

Replace the counter with a table or subtable and get the number style you want.
Example:

\renewcommand{\thefigure}{\roman{figure}}
\renewcommand{\thesubfigure}{\arabic{subfigure}}

\begin{ Figure}	
	\centering
	\begin{subfigure}[t]{1in}
		\centering
		\includegraphics[width=1in]{ PLACEHOLDER}
		\caption{arabic numerals}\label{fig:1a}		
	\end{subfigure}
	\quad
	\begin{subfigure}[t] {1in}
		\centering
		\includegraphics[width=1in]{placeholder}
		\caption{arabic numerals}\label{fig:1b}
	\end {Subfigure}
	\caption{capital Roman numerals}\label{fig:1}
\end{figure}

The icon number is associated with the chapter.

Similar to the following code

% This applies if your have chapters

\renewcommand{\thefigure}{\thechapter.\alph{figure}}% set caption label style to 1.A
\renewcommand{\thesubfigure}{\arabic{subfigure}}

\begin{figure}	
	\centering
	\begin{ subfigure}[t]{1in}
		\centering
		\includegraphics[width=1in]{placeholder}
		\caption{arabic numerals}\ LABEL{FIG:1A}		
	\end{subfigure}
	\quad
	\begin{subfigure}[t]{1in}
		\centering
		\ Includegraphics[width=1in]{placeholder}
		\caption{arabic numerals}\label{fig:1b}
	\end{subfigure}
	\caption{chapter number dot Figure letter}\label{fig:1}
\end{figure}

Heading style settings

When you import a macro package, you can set the global style directly, that is, all caption styles change, as shown in the following example:

% options apply to all captions
\usepackage[options]{caption}

% applies to all subfigure and subtable captions
  \usepackage[options]{subcaption}

% would apply to all captions
\usepackage[labelfont=it,textfont={bf,it}]{caption}

% would apply to all subcaptions
\usepackage[labelfont=bf,textfont=normalfont,singlelinecheck=off,justification=raggedright]{subcaption}

You can also use \captionsetup to set the heading style so that all subsequent heading styles are reset according to \captionsetup, and the sample code is as follows:

\captionsetup[float_type]{options}

Float_type can be table, subtable, figure, Subfigure, and so on, the following code shows the settings for label font, text font, and the alignment of subheadings:

% for figures:caption label are italic, the caption text is Bold/italic \captionsetup[figure]{l
Abelfont=it,textfont={bf,it}}% for Subfigures:caption label is bold, the caption text normal.  % justification is raggedright (i.e. left aligned)% Singlelinecheck=off means this justification setting is used even 
When the "caption is" a single line long.
% if singlelinecheck=on, then caption is always centered the caption was only one. \captionsetup[subfigure]{labelfont=bf,textfont=normalfont,singlelinecheck=off,justification=raggedright} \begin {figure} \centering \begin{subfigure}[t]{1in} \centering \includegraphics[width=1in]{placeholder} \caption{Captio N}\LABEL{FIG:1A} \end{subfigure} \quad \begin{subfigure}[t]{1in} \centering \includegraphics[width=1in]{placeholder } \caption{caption}\label{fig:1b} \end{subfigure} \caption{main figure caption.} \label{fig:1} \end{figure} 

Operation effect is as follows

Where Singlelinecheck=off is to set the justification setting for even a row of headings, otherwise the default is centered.
The header size is set as follows

\captionsetup{font={scriptsize}}
