A full caption includes, whenever available & appropriate, information in the following order:
Caption written in AB Style:

Place images as close as possible to the parts of the text to which they relate. The image should be labeled as Figure (usually abbreviated Fig.), assigned an arabic numeral and given a caption. A label and title or caption ordinarily appear directly below the illustration and have the same one-inch margins as the text of the paper. Captions should be numbered consecutively.
