Figure and table legends should be provided on a separate sheet, double spaced and numbered separately in order of appearance in the text. Legends and / or captions should be provided for every figure or image; these should be short, descriptive and should define any acronyms, abbreviations or symbols used. They should begin with a brief title for the whole figure and continue with a short description of each panel. The key should not be part of the legend.

Figures

Number figures with Arabic numerals in order of appearance. Line drawings should be high-quality laser output (not photocopies).

When submitting artwork, reduction to the scale that will be used on the page is unnecessary. However, it should be borne in mind that figures will be resized to fit one or two column-widths (3.5" and 7" respectively) of the journal page, and the figure and its labelling should be clear and legible at this size. No figures should exceed 8.5" by 11" in size.

Rules should be no thinner than 1 point (0.36 mm) after size reduction. In graphs, a coarse pattern such as hatching should be used because shading and tints are liable to break up on the printed copy. Figures divided into parts should be labelled with a lower-case, bold a, b, etc in the top left-hand corner.

The journal is printed in black-and-white. Therefore, we prefer that you supply your figures in greyscale. Figures supplied in colour will be converted to greyscale for print unless the author confirms they will cover the cost of printing in colour (costs available from the production/editorial office). You may however request for any/all figures to be shown in colour in the HTML (web) version of your article, but bear in mind that the PDF/print version will still be black-and-white, so please make sure that colour is not critical to understanding any figures; and do not describe elements of the figure in terms of their colours. For example line graphs with several data series can usually be represented adequately in black-and-white by using different line styles and/or different shaped nodes.

Tables

Number each table consecutively with Arabic numerals and double space them on separate pages. Avoid using vertical rules. Horizontal rules should be used only above and below column headings and at the bottom of the table.
