Unique values color mode is available for columns in continuous scale mode. It is similar to the Categorical color mode, and gives each unique value in the column a separate color, as seen in the example below.
In the example, the scatter plot is colored by the column Sales, which is a column containing integer values. Each unique value in the column has its own color. The example below shows the Colors page of the Visualization Properties for Unique values color mode.
Changing the color for values
To change the color of any of the values in the color scheme, click on the color box to the left of a value. A color selector will appear, and you can select a different color.
Adding rules to the color scheme
You cannot add points to the color scheme in Unique values mode, but you can add rules. A rule functions as an exception to the rest of the color scheme. For example, you can add a rule stating that the bottom three values should be yellow. In the example above, this would mean that the values 8, 9, and 10 would all be yellow. To add a rule, click on the Add Rule... button to the right of the color scheme area. This will open a dialog where you can define the rule. The rule will be added at the top of the color scheme as seen below.
If the color scheme includes more than one rule, the rules are prioritized from top to bottom. You can change the order of the rules by using drag-and-drop. To learn more about rules in color schemes, see Color Rules Overview.
Deleting rules
To delete a rule, click on the x to the right of the rule, or right-click on the rule and select Delete Rule from the menu.
Resetting the color scheme
To reset the color scheme to its initial state, right-click in the color scheme area to open the menu, and select Reset Color Scheme. The color scheme will be reset to the default state for the selected column. Any added rules will be removed.
Note: A color scheme in Unique values color mode may appear as if the coloring is categorical. However, because the column used to color by is in continuous scale mode, the coloring is also considered continuous. This means that if you are using multiple scales, it is not possible to set individual scaling per color. For lines and curves, this means that you cannot set them to one line or curve per color.
