Selection : You can choose here to not highlight the selected item (slice/marker/line…). If highlighted, you can set the color of the selection. You can also choose to add a button in the N4V menu to reset the selection : the action on the button will go back to the top level of the chart (if the component is drillable) and deselect all previous selection.
