Dial gauges are excellent for tracking progress or completion rates. Critical success factor, GPA or performance score analyses are common examples.
A dial 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, determine the low and high Ranges for each selected field, as well as a dial Color.
In the Format tab, you can add Trends to be displayed on the gauge. Trends are very useful for adding a comparison scale to gauges.
