Captioning Figures Without Floats In Latex

Adding Captions Without Floats

LaTeX provides extensive capabilities for adding captions to figures and tables using floats. However, floats can sometimes be problematic and result in misplaced or out-of-order captions. An alternative method is to caption figures without using floats at all. This involves using the caption package and placing captions directly in the text flow instead of letting LaTeX determine their optimal placement.

Captioning without floats gives more precise control over caption positioning. It also avoids common float issues like figures appearing pages away from their captions. The main tradeoff is captions without floats require manually fixing any alignment or spacing issues that arise. With some customized styling and tweaking however, high-quality captions can be added without floats.

What are Floats and Why Avoid Them for Captions

In LaTeX, floats are objects like figures, tables, algorithms, etc. that float to positions in the text LaTeX determines as optimal. Floats have captions, are numbered, and can span pages. LaTeX tries spacing floats well and situating them where it thinks readers will best comprehend associations between floats and surrounding text.

LaTeX float positioning algorithms work nicely when documents have a regular structure. But for complex documents, suboptimal float placement can happen, causing captions and figures to be misaligned or separated by many pages of text. Excess floats also strain the positioning algorithms, increasing errors. Float limitations can therefore incentivize captioning without using floats at all.

Additionally, the fine positioning control provided by captions without floats can be beneficial. Figures can be precisely situated close to their explanatory text instead of pages away. Manual spacing around captions can be inserted instead of hoping floats place optimally. The absolute positioning enables prioritizing sensible associations between concepts, objects and captions over LaTeX automated judgments.

Common Float Limitations

  • Figures placed far from captions
  • Captions breaking across pages
  • Floating objects appearing out of order
  • Too many floats overwhelming position algorithms
  • Manual float positioning complicated and unwieldy

Benefits of Captioning Without Floats

  • Precise control over caption placement
  • Figures and captions remain together
  • Avoid unexpected float behavior
  • Simplify document structure and reduce errors
  • Prioritize logical concept associations

Using the caption Package Without Floats

The caption package enables captions without floats in LaTeX. It provides commands for customized caption styling, numbering, and positioning without tying captions directly to float environments.

To caption without floats, first include the caption package in the document preamble. Then use the \captionof command along with desired caption style options to add captions. The general syntax for \captionof is:

\captionof{type}[numbered-label]{caption text}

Here {type} is the object being captioned like "figure" or "table". The [numbered-label] parameter is for an optional custom numbered label. And {caption text} contains the descriptive text for the object. Some examples:

\captionof{figure}{An informative sample figure}
\captionof{table}[descriptive-key]{Relevant data for analysis}

These caption commands can be situated anywhere appropriate in text or next to included graphics without needing float environments. The captions will be numbered and styled based only on commands instead of floats.

Key Advantages of caption Package for Non-Floating Captions

  • Works without floats using basic LaTeX document classes
  • Customizable caption numbering and text font styles
  • Multiple independent numbering sequences
  • Optional precise positioned for figures and captions
  • Configurable space before and after captions

Strategies to Employ Caption Package Effectively

  • Load package in preamble with \usepackage{caption}
  • Leave wide margins to help situate images/tables
  • Use indentation and spacing for clean look around captions
  • Break text into lines or paragraphs when placing captions
  • Set space above and below captions for clarity

Positioning Captions Without Floats

Positioning non-floating captions requires manually fixing spacing and alignment unlike LaTeX automated float positioning. Strategic placement choices are therefore important for high-quality, readable documents.

Captions without floats should be entered directly alongside their corresponding figures and tables within the normal text flow. Insert an empty line before and after captions to cleanly separate them from body text. Use indentation and line breaks to integrate captioned objects with adequate spacing.

If using an environment like {center} to horizontally center figures, tables, etc., be sure to situate captions within the same environment so alignments match. The same applies to vertically oriented environments like {sideways} or {rotatebox} to achieve proper caption orientations.

Common Positions for Non-Floating Captions

  • Centered captions - Place image and centered caption together between text. Allows objects to span page width if needed while keeping association clear.
  • Side captions - Insert caption text in an inside margin, aligned with side-set image/table. Keeps related objects visually paired together.
  • Indented captions - Set caption directly following reference in text with indentation for distinction from body text.
  • Column spanning captions - Have objects and captions encompass both text columns. Useful for wide elements in multicolumn layouts.

Guidelines for Positioning Non-Floated Captions

  • Place captions immediately alongside relevant objects
  • Separate caption from body text with blank lines before and after
  • Use environments like {center} consistently for captions and objects
  • Indent captions under objects without space when possible
  • Break text into paragraphs/lines to integrate captions cleanly

Customizing Caption Styling Without Floats

The caption package provides commands to customize caption text and numbering without needing floats. Options like font styles, caption prefixes, and spacing can be configured.

To setup captions, the \captionsetup command is used in the preamble. General syntax is:


Here {type} is the captioned object like "figure" or "table". {Options} contains desired formatting configurations. Some examples adjustments:


These commands customize all figure captions, all table captions, and global options respectively. The customizations will apply automatically to relevant \captionof usages in the document body text.

Useful Caption Customization Options

  • font - Sets caption text font style
  • labelfont - Defines font of caption number label
  • labelsep - Configures separator between number and text
  • indent - Sets indent space for caption text
  • aboveskip/belowskip - Space above/below caption

Strategies for Stylized Non-Floating Captions

  • Use small font to subtly integrate captions with text flow
  • Customize label font (bold/italic) to make numbers stand out
  • Add indent for caption text to distinguish from body content
  • Set skip space around captions for cleanliness and clarity
  • Left-align numbers but justify caption text to body width

Troubleshooting Issues with Captioning Without Floats

Captioning figures, tables, and other objects without using floats requires manually working out alignment, spacing, sizing, and font style issues. But using common troubleshooting techniques can help resolve potential formatting problems.

Debugging Caption Layout and Style Problems

Try these general fixes for non-floating caption difficulties:

  • Overlapping objects/captions - Adjust indents and insertion of blank lines for separation space
  • Mismatched alignments - Use consistent environments like {center} for objects and captions
  • Small text fonts - Increase font size for improved readability if needed
  • Caption width issues - Specify {justification} settings as needed to adjust wrapping and width
  • Runaway spacing - Reduce default {aboveskip} and {belowskip} if space is excessive

Specific Non-Floated Caption Fixes

  • Scale down oversized graphics forcing captions off area
  • Widen/narrow caption width using \captionsetup[type]{width=Xcm}
  • Add vertical space with \\[2ex] between caption and preceding text
  • Separate caption label/text onto own lines to isolate style options
  • Right-align run-in figure captions to body text using \raggedleft

With some targeted troubleshooting and styling adjustments, common captioning problems can typically be systematically corrected.
