Understanding LaTeX Figure Management

The Float System

LaTeX treats figures as “floats”—elements that can move to optimize page layout. This sophisticated system ensures professional document appearance but requires understanding to master:

% Basic figure environment
\begin{figure}[placement specifiers]
    % Figure content
    \caption{Figure description}
    \label{fig:unique-label}
\end{figure}

Placement Specifiers Explained

\begin{figure}[htbp]
% h - here (approximately at this position)
% t - top of page
% b - bottom of page
% p - separate page for floats
% ! - override LaTeX's internal parameters
% H - HERE (requires float package)

Pro tip: Use [htbp] for most figures, allowing LaTeX maximum flexibility.

Including External Graphics

Basic Image Inclusion

First, load the graphicx package:

\usepackage{graphicx}

% Optional: Set graphics path
\graphicspath{{images/}{figures/}{../assets/}}

Include images with:

\begin{figure}[htbp]
    \centering
    \includegraphics[width=0.8\textwidth]{experiment-results.png}
    \caption{Experimental results showing quantum entanglement}
    \label{fig:quantum-results}
\end{figure}

Advanced includegraphics Options

% Size control
\includegraphics[width=5cm]{image.jpg}
\includegraphics[height=3cm]{image.jpg}
\includegraphics[scale=0.5]{image.jpg}

% Maintain aspect ratio
\includegraphics[width=0.5\textwidth,keepaspectratio]{image.jpg}

% Rotation and clipping
\includegraphics[angle=90,origin=c]{image.jpg}
\includegraphics[trim=1cm 2cm 1cm 2cm,clip]{image.jpg}

% Advanced example
\includegraphics[
    width=0.7\textwidth,
    angle=15,
    origin=c,
    trim=0.5cm 0.5cm 0.5cm 0.5cm,
    clip
]{complex-diagram.pdf}

Supported Image Formats

% PDFLaTeX supports:
% - PDF (vector, preferred for diagrams)
% - PNG (raster, good for photos)
% - JPG/JPEG (raster, compressed photos)

% XeLaTeX/LuaLaTeX additionally support:
% - EPS (with conversion)
% - SVG (with svg package)

        box/.style={rectangle, draw, rounded corners, 
                    minimum width=3cm, minimum height=1cm},
        arrow/.style={->, thick}
    ]
        % Nodes
        \node[box] (input) {Input};
        \node[box, right=of input] (process) {Process};
        \node[box, right=of process] (output) {Output};
        
        % Arrows
        \draw[arrow] (input) -- (process);
        \draw[arrow] (process) -- (output);
        
        % Labels
        \node[above=0.5cm of process] {System Overview};
    \end{tikzpicture}
    \caption{Simple system diagram}
    \label{fig:system}
\end{figure}

Scientific Plots with pgfplots

\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\begin{figure}[htbp]
    \centering
    \begin{tikzpicture}
        \begin{axis}[
            xlabel={Time (s)},
            ylabel={Amplitude},
            grid=major,
            width=0.8\textwidth,
            height=6cm,
            legend pos=north east
        ]
            % Plot from data
            \addplot[blue, thick] coordinates {
                (0,0) (1,2) (2,3) (3,3.5) (4,3.8) (5,4)
            };
            \addlegendentry{Experimental}
            
            % Plot from function
            \addplot[red, dashed, domain=0:5, samples=100] 
                {4*(1-exp(-0.5*x))};
            \addlegendentry{Theoretical}
        \end{axis}
    \end{tikzpicture}
    \caption{Comparison of experimental and theoretical results}
    \label{fig:plot-comparison}
\end{figure}

Flow Charts and Diagrams

\usetikzlibrary{shapes.geometric, arrows.meta}

\begin{figure}[htbp]
    \centering
    \begin{tikzpicture}[
        node distance=2cm,
        startstop/.style={rectangle, rounded corners, 
            minimum width=3cm, minimum height=1cm,
            text centered, draw=black, fill=red!30},
        process/.style={rectangle, minimum width=3cm, 
            minimum height=1cm, text centered, 
            draw=black, fill=orange!30},
        decision/.style={diamond, minimum width=3cm, 
            minimum height=1cm, text centered, 
            draw=black, fill=green!30},
        arrow/.style={thick,->,>=stealth}

        \node[startstop] (start) {Start};
        \node[process, below of=start] (init) {Initialize};
        \node[decision, below of=init] (decide) {Condition?};
        \node[process, below of=decide, xshift=-3cm] (yes) {Process A};
        \node[process, below of=decide, xshift=3cm] (no) {Process B};
        \node[startstop, below of=decide, yshift=-3cm] (stop) {End};
        
        \draw[arrow] (start) -- (init);
        \draw[arrow] (init) -- (decide);
        \draw[arrow] (decide) -- node[left] {Yes} (yes);
        \draw[arrow] (decide) -- node[right] {No} (no);
        \draw[arrow] (yes) |- (stop);
        \draw[arrow] (no) |- (stop);
    \end{tikzpicture}
    \caption{Algorithm flowchart}
    \label{fig:flowchart}

Managing Complex Figures

Wrapping Text Around Figures

\usepackage{wrapfig}

\begin{wrapfigure}{r}{0.4\textwidth}
    \centering
    \includegraphics[width=0.35\textwidth]{molecule.png}
    \caption{Molecular structure}
    \label{fig:molecule}
\end{wrapfigure}

This text will wrap around the figure. The wrapfigure environment 
is particularly useful for small figures that don't need the full 
text width. Continue writing your paragraph here...

Full-Width Figures in Two-Column Documents

\begin{figure*}[htbp]
    \centering
    \includegraphics[width=\textwidth]{panoramic-view.png}
    \caption{Full-width figure spanning both columns}
    \label{fig:fullwidth}
\end{figure*}

Landscape Figures

\usepackage{rotating}

\begin{sidewaysfigure}
    \centering
    \includegraphics[width=\textwidth]{wide-table.png}
    \caption{Rotated figure for landscape orientation}
    \label{fig:landscape}
\end{sidewaysfigure}

Optimizing Figure Quality

Resolution Guidelines

% Print quality: 300 DPI minimum
% Screen viewing: 150 DPI acceptable

% Calculate required pixel dimensions:
% Width in inches × DPI = pixel width
% Example: 6 inches × 300 DPI = 1800 pixels wide

Vector vs Raster Graphics

% Use vector formats (PDF, EPS) for:
% - Diagrams
% - Charts
% - Line drawings
% - Text-heavy graphics

% Use raster formats (PNG, JPG) for:
% - Photographs
% - Screenshots
% - Complex gradients
% - Scanned images

% Converting formats:
% inkscape input.svg --export-pdf=output.pdf
% convert input.png output.pdf

Color Management

\usepackage{xcolor}

% Define custom colors for consistency
\definecolor{primaryblue}{RGB}{0,102,204}
\definecolor{secondaryred}{RGB}{204,0,0}
\definecolor{accentgreen}{RGB}{0,153,0}

% Use in figures
\begin{tikzpicture}
    \draw[color=primaryblue, thick] (0,0) -- (2,2);
    \fill[color=secondaryred] (1,1) circle (0.1);
\end{tikzpicture}

Troubleshooting Common Issues

Figure Placement Problems

% Force figure placement
\usepackage{float}
\begin{figure}[H]  % Capital H forces "HERE"
    \includegraphics{urgent-figure.png}
\end{figure}

% Clear all pending floats
\clearpage  % or \cleardoublepage for books

% Adjust float parameters
\setcounter{topnumber}{3}
\renewcommand{\topfraction}{0.9}
\renewcommand{\textfraction}{0.1}

Missing Figures

% Debug missing figures
\usepackage[draft]{graphicx}  % Shows frames with filenames

% Check file paths
\graphicspath{{./images/}{../figures/}{/absolute/path/}}

% List loaded files
