I have a colour scale, used as a legend for a choropleth, that looks like this:
The legend represents distance from the mean.
However, the ends of the scale are not clamped - the uppermost range may include values that are greater than x2, and the lowest range may include values less that x0.1.
What is the correct way to display this the the user? I've had multiple attempts, but feel that the outcome is lacking and my testers have found each to be misleading.
Things I've tried:
<x0.1 ... x2< -x0.1 ... x2+ -100% ... +100%
