It seems that every single time it is one of those. Seriously, though, just the manner in which graphs are presented can make a big difference in interpretation, even without manipulation or photoshop. For example, leaving out the origin for ratio data, or plotting two curves overlaid instead of plotting the difference.

I'm afraid I'm so old it would never occur to me to do that. Whatever my old FORTRAN program cranked out is how the imaging software presented it. We might rotate the molecular image to show a different view, but that's about the extent of enhancement that ever occurred to us. And trust me, there were times when my images could have used some "clarity". In fact, there were a lot of times my publications could have used a lot more clarity, based on the rejection notices and request for clarification notifications. :-) Holy cheating batman.
