<fig> Figure

Block of graphical or textual material that is identified as a figure, usually bearing a caption and a label such as “Figure 3.” or “Figure”.


A <fig> is defined as an element that would appear in the Table of Figures, if there were one.
The content of a <fig> need not be graphical in nature; the content of a figure may be a graphic, a list, several paragraphs, an equation, a display quote, a table, etc., or a mixture of several of these.
The @position attribute may be used to indicate whether this element must be anchored at its exact location within the text or whether it may float (for example, to the top of the next page, into the next column, to the end of a logical file, or within a separate window).

Best Practice

Tag unlabeled graphics as <graphic> elements rather than as <fig> elements. A common test to determine if an object is a <fig> versus a <graphic> is to ask, “If there were a “List of Figures” for this document, should this object appear in that list?”
Associating Supplementary Data with a Figure
When the data (such as a spreadsheet or dataset) associated with a document has been described using a <supplementary-material> element, then a figure can use an internal <xref> to point to that <supplementary-material>. This provides a mechanism to expose the data behind the figure. For example, assume that a figure (<fig>) is associated with three pieces of supplementary material (each described in a <supplementary-material> element). Three cross references (<xref>) can be embedded in the figure tagging to associate the figure with all three supplementary items, which may be datasets, additional figures, spreadsheets, etc. Note that a figure and its three supporting data objects are described in one figure and three supplementary material objects, which are connected by internal cross-references (<xref> elements), rather than as a figure group (<fig-group>) even if the 3 associated objects are figures.
Each figure within a <fig-group> may contain its own <xref> elements to make this internal connection. In addition, the figure group as a whole may contain internal cross-references of its own. External connections can also be made using one or more <ext-link> elements within a figure or table tagging.
Multi-language Figure/Tables
JATS provides several ways to tag tables, figures, etc. in multiple languages. The element <block-alternatives> can be used to hold two or more versions of the table or figure, each in a different language. It is also possible to place multiple <label> and <caption> elements inside a single figure or table, one label and caption for each language, differentiated by @xml:lang attributes. In the case of double labels and captions, the content of the figure is not repeated, only the labels and captions.
