# Dictionary and Thresholds

In case the metric is of type numeric, you can additionally specify the *Data Type*, which can be:

- *CONTINUOUS*: The metric represents a physical measure that is continuously measured and saved (e.g., a temperature). Therefore, the metric can take on any numerical value.
- *DISCRETE*: The metric is a code that represents a specific state. Therefore, the metric can take any numeric value within a predefined set (e.g., 1,2,3).

Depending on the chosen Data Type, a Dictionary (DISCRETE) or Thresholds (CONTINUOUS) in a range of values can be defined.

# Dictionary

In case of *DISCRETE* data type, you can define a dictionary to map values.

By clicking *Add Dictionary Item*, a new item is added to the list, and for each item you can define:

- *Value*: the mapped value. In case the metric is BOOLEAN you must use `true` or `false` as values.
- *Label*: the label to be displayed as an alternative to the value.
- *Severity*: the severity of the item used to color the values or labels.
- *Icon*: the [Material Icon](https://fonts.google.com/icons) to be displayed next to the label or value.

For more details about how to display values with a dictionary, refer to the [Dictionary](/docs/dictionary-filter) filter.

# Thresholds

In case of *CONTINUOUS* data type, other than, the minimum and maximum values, you can define the Thresholds.

By clicking *Add Threshold*, a new threshold is added to the list, and for each threshold you can define:

- *Max Value*: the maximum value of the threshold.
- *Label*: the label to be displayed as an alternative to the value in case it falls within the threshold.
- *Severity*: the severity of the threshold used to color the values or labels.
- *Icon*: the [Material Icon](https://fonts.google.com/icons) to be displayed next to the label or value in case the value is in this threshold.

For more details about how to display values with thresholds, refer to the [Dictionary](/docs/dictionary-filter) filter.

Thresholds are then also used by widgets to highlight the value, for instance, the [Value](/docs/value-widget) widget.
