Implying Comparison

This kind of data presentation strikes me as close to disingenuous. I understand that somewhere in someone’s mind, the thought is to maximize the width of the diagram, but when all the measures are the same, these all represent percent changes of opinion among the same population responding to the same survey, then the shift in scale actually misleads readers, who easily see the big red bars, that there has been large changes across the board. Instead, there’s been changes of 20%, 15%, and 7%. Those differences in size are hard to read with the light gray numbers up above, almost lost under the bold black of the diagram’s title.

You can do better, The Guardian.
