This class includes fields that display a contiguous range of integer values represented as a scale. All analog fields have a minimum and maximum integer value. The current value of the variable scales the display relative to the minimum and maximum values. However, if the value is greater than the maximum value, then the value will equal the maximum value.

The most common type of analog field for user input is the slider field, which lets the user drag a slider to set the value. The bar field is often used within table fields to display bar charts. The independent scroll bar field is rarely needed, as OpenROAD provides scroll bars where they are commonly needed. However, you may need to create independent scroll bars for some advanced applications.

Variables associated with the AnalogField class are of type integer.
