The Bamboo Visual Indicator gives you two simple methods for displaying list data graphically, depending on the type of data. Visual Indicator columns are essentially display-only columns tied to traditional list columns; if you want to add or change list values do so in the normal choice, lookup, or percentage columns, and these changes are reflected in the visual indicators. You can then hide the traditional, non-visual columns, and display the easier-to read-Visual Indicator columns instead.
