A chart word, with the charts that use it.
Definition

Common mistakes
A midpoint that is not meaningful
Diverge from zero or from a target, not from the average by default.
One colour for both sides
Gains and losses blur together. Give each side its own colour.
Questions
When is a diverging scale the right choice?
When the sign matters: in and out, agree and disagree, above and below target.
Does each side need the same length?
Yes, so the two directions compare fairly.
