Scale properties define the range of values and the number of tick marks that a gadget displays. The scale properties affect the numbers displayed on the gadget, not its size. Minimum Value and Maximum Value specify the lowest and highest numbers, respectively. However, if the data set value (represented by the needle value) is lower than the minimum value or higher than the maximum value, the minimum or maximum value is ignored. Table 8‑4 describes the scale properties you can modify using Interactive Viewer.
