A scale that does not start at 0, or that has unequal gaps — differences between bars look bigger than they are.

In 'write down one thing wrong with this bar chart', what kind of answer earns the mark?

A genuine error in the diagram, e.g. a bar drawn at the wrong height so it does not match the table, or a missing axis label/scale.
