  1. In writing my thesis in geosciences I have a number of figures with a fair amount of text content. Is there some limit I should adhere to -- say for example max 5 lines -- before I should just write 'refer to text'?
  2. A related question is where citations should go, especially in the case of several needed for one figure (e.g. a plot of n sets of data from n different sources). Again, is there some point where I should say refer to text for citations?

Usually, these things are specified in the style guide for the thesis at your institution. If not, then you can probably do whatever you like. – Suresh Dec 13 '12 at 1:03
No mention of it in our handbook, so I guess I'll make it up as I go along :) – a different ben Dec 13 '12 at 4:44
The desire for a long caption is often an indicator of an overly complex figure. – Daniel E. Shub Dec 13 '12 at 10:20

I would imagine this may vary from field to field, but in the biological sciences the caption text in journal publications is often verbose to the point of absurdity. That being said, I would simply use common sense; If the description takes more than a paragraph, you should definitely "refer to text". Generally speaking, the caption is simply a textual guide as to how to read the plot, with (maybe) a sentence drawing the reader's attention to a particular feature of the plot. It should mostly describe the plot, and only sparingly discuss it.

The only guidance I've ever been given on figures is that a reader should be able to understand them in isolation from the text. Ideally to me the caption should capture the essence of the figure. – a different ben Dec 13 '12 at 4:48

+1 for "only sparingly discuss it". The caption needs to help readers understand your data, not your conclusions. The following are all fine things to include in a caption: a brief description of how the data were collected and/or processed, why you chose a logarithmic scale instead of a linear one, the difference between open and closed symbols, why there is a big circle around the rat's head in picture 4, etc. Any straying into the realm of interpretation belongs in the body, not in the caption. – Ben Norris Dec 13 '12 at 20:52

An expert in the field should be able to understand most of the content of the figure from the figure and caption alone. The caption should be long enough to admit this, but no longer. If your captions seem to need to be pages long, then you need to work on making your figure adhere better to standards in the field or to be intuitively clearer.

If you run out of time to make it comprehensible, keep the caption comfortably smaller than the figure itself; having a tiny figure with a huge block of text just looks wrong. It takes a long time to make really clear figures, but you can at least get the superficial style right quickly enough.

+1 for the comment about time. Making well-designed figures, with high information content per square inch but simultaneously readily understandable, requires a lot of work. From my experience in neurobiology, it often takes longer to prepare the figures than the text of the manuscript. – eykanal♦ Dec 14 '12 at 3:00
