Currently, you are not able to use a data item for interval expressions when creating a gauge display rule where colored icons are an option. You can use a data item for comparison when creating expression display rules, and you could create multiple expression-based rules for a given list table column to simulate range intervals. However, the data item must come from the same source table. Note that with expression display rules, you can only style the value, such as font color, bold, etc. Colored icons are only available with the gauge display rules.
