Digital gauges act like an interactive display card; they show a quantity in a fancy way. This gauge can be used to report inventories or “X Interval to Date” totals.
A digital gauge requires at least one Data Field. When you select more than one field, these will be shown on new gauges in the order you place them on Selected Data.
Please note that the any data you select needs to contain numeric fields and remember to select an Expression for each field by clicking on the field first and then choosing from the drop down.
Next, select a Color for each data field. In the Format tab, you can also add Trends to be displayed on the gauge. Trends are very useful for comparison purposes and these icons can help you make better sense of these numbers.
