Diverging Color Palettes

Diverging Palettes use a three color gradient between a minimum, middle and a maximum value. Numeric columns containing both positive and negative values default to the Diverging Palette with the Red White Blue color palette selected.

Diverging Palettes use the Range Midpoint. The Min, Mean, and Max points are populated with defaults from the data set.
