Creating a Sequential or Diverging Numeric Color Palette
Panopticon visualizations support two types of Numeric Color Palettes: Sequential and Diverging.
q Sequential Color Palettes
Sequential palettes use a two-color gradient between a minimum and a maximum value. Numeric column containing only positive values default to a Sequential Palette using the White-Blue color palette.
In this case the range Mid point is disabled, and the Min and Max points are populated with defaults from the data set.
q 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, Mid and Max points are populated with defaults from the data set.
