Place all legends (including title for each) together on one page. Figures are consecutively numbered with Arabic numerals (Fig. 1, 2, etc.), according to the order of appearance in the main text. Legends should provide enough information so that the figure is understandable without frequent reference to the text. However, detailed experimental methods must be described in the Materials and Methods section, not in a figure legend. A method that is unique to one of several experiments may be reported in a legend only if the discussion is very brief (one or two sentences). Define all symbols used in the figure and define all abbreviation that is not used in the text. A maximum of 6 figures and tables (total) is allowed.
