Color

The Color property settings enhance markers and features by either applying different colors to column values (for discrete categorical items), or by applying a color gradation (for continuous data). Color options include built-in schemes.

Property setting Default value Description
Color by None Specifies that the color is determined by the selected column in the data.
One scale per None Specifies whether each trellis panel should have a separate color scale. Applies only to trellis visualizations and if the specified columns have continuous data.
Add color rule None Sets exceptions from the current coloring according to how you specify the rule. See Adding a rule to color scheme for more information.
Color scheme None Lists the predefined color schemes available for the type of data in the column.
Color items values Lists the colors assigned by the selected color scheme to the items specified by the selected Color by column.

Color example

This map chart visualization shows a trellis map of Sweden with various color rules applied to both the feature layer (Swedish counties) and the marker layer (Swedish county capitals). The three largest cities (those over 200,000) are in the trellis panel closest to the legend.


Color rules for both counties and county capitals.

Tip: You can customize the colors of markers or features from the legend. In the legend, click the color icon that you want to change, and from the color picker, select a new color. If you change a color for an icon representing the maximum and minimum of a continuous range, all colors between the ranges shift to adjust to a scale between the two resulting colors.
