Adding a Color Legend

The Color Legend displays the color variables of the associated visualization. You can also set the orientation and style or enable the ability to do a filter or to display this part in the PDF output.


1.     After double-clicking or drawing a rectangle on the dashboard canvas, click  on the Select Part pane then click the Color Legend   icon.

The Color Legend Settings pane is displayed, and the Color Legend part is added on the dashboard canvas.


2.     Select any of the available parent visualizations with color variable from the Linked Part drop-down list.

The color legend is  connected to its parent visualization and the link between them is displayed. The color variables are retrieved from this visualization and displayed in the legend.


If the visualization can display multiple color variables, which is the case with the Table and Time Combination, then the legend displays a drop list of possible variables to display.


There are two Color Legend styles:

·         Categorical

The categorical style color legend lists all text categories and colors used in the associated visualization for the selected source column.

·         Numeric

The numeric style color legend displays the color range used within the associated visualization for the selected numeric source column.

The style displayed depends on the active color variable of the linked visualization.

3.     Set the color legend to All Colors or to a specific source column.

4.     The style of a Numeric Color Legend can be fixed either:

·         Continuous

·         Discrete
