I’ve written here before about one of my proposal bugbears – overly-lengthy captions for proposal graphics, which distract from the flow of the document. I’m on something of an anti-caption campaign altogether at the moment, having reflected at length on the advice in the APMP Foundation exam that a great caption should “invite the reader to draw the correct conclusion from the graphic”.
See, if your graphic is good enough, you shouldn’t need a caption to help the reader to draw the correct conclusion: that conclusion should be evident and obvious from the graphic itself.
