Caption or title: which should I use?
What is your paper for? I think figures (for example in journal articles or thesis) usuaully have a caption below them, in addition to their number:


  Figure 1.  Cumulative food intake in rats during intragastric treatment


But typically there is no "title", unless you have a "list of figures" somewhere in the beginning of the document: then it is ok to use the same phrase as caption and title, because they are not written at the same place.
