[Tex/LaTex] How to put two figures in the same page

floats

enter image description here

I am trying to put two figures in the same page of my paper, but although there is still enough space for the second figure in the first page, the second picture won't appear in the first page. Anybody can help?

Meanwhile, we also generate figures about the distribution of debris based on size (\textbf{Figure 5}, \textbf{Figure 6}). 
\begin{figure}
    \centering
    \includegraphics[width=0.8\textwidth]{1cm-10cm.png}
    \centering
    \caption{Spatial density of space debris ranging from 1cm to 10cm.}
\end{figure} 
\begin{figure}
    \centering
    \includegraphics[width=0.8\textwidth]{10cm.png}
    \centering
    \caption{Spatial density of space debris larger than 10cm.} 
\end{figure}

Best Answer

Some notes:

  • To solve your issue, to each figure add \begin{figure}[!htb]
  • Only one \centering is enough inside a figure/table environment, so you can remove the second one in each.
  • The "Figure 5 and Figure 6" you manually added can be done automatically by Latex, by adding \label{<your label>} inside of each figure then writing \ref{<your label>} or \cref{<your label>} (with the cleveref package) in the text. The label is of course, arbitrary.

cleveref offers some ways to customize your labels. For example

  • \cref{} = fig.
  • \Cref{} = Fig.

If you want to make all of them capitalized, then add capitalise to the package options. With a couple of additional commands we can make all of that bold, but I strongly suggest you don't use this because it will be too highlighted compared to the text.

Here's an example:

enter image description here

\documentclass{article}
\usepackage{graphicx}
\usepackage[capitalise]{cleveref}

\crefdefaultlabelformat{\textbf{#2#1#3}}
\crefname{figure}{\textbf{Fig.}}{\textbf{Figures}} 

\begin{document}  
Meanwhile, we also generate figures about the distribution of debris based on size (\cref{top}, \cref{bottom}). 
\begin{figure}[!htb]
    \centering
    \includegraphics[width=0.8\textwidth]{example-image-a}
    \caption{Spatial density of space debris ranging from 1cm to 10cm.}
    \label{top}
\end{figure} 
\begin{figure}[!htb]
    \centering
    \includegraphics[width=0.8\textwidth]{example-image-b}
    \caption{Spatial density of space debris larger than 10cm.} 
    \label{bottom}
\end{figure} 
\end{document}
