Honestly this axis is pretty good. It's scaled for easy reading, the scales are identical for both, there's not logarithmic or power scaling going on, etc. A fixed jump, solidly different colors that aren't TOO associated with normal western biases (red bad, green good; this is pastels so somewhat escapes that), scaling accurately without visual tricks. For this data this is a really good graph. Read some Edward Tufte or the like to get an idea of what bad and good visual displays of information look like.
