Like other gauge types, linear gauges too are great for tracking progress or completion rates. They closely resemble a bullet diagram. Sales, budgeting or inventory analyses are common examples.
A linear gauge requires at least one Data Field. You can also add a Marker Field to each field selection. 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.
