Dashboard-Element
Represents a field within a dashboard configuration, which can be used as category or series value.
The data field of a dashboard field must correspond to a field in the source data items.
Configuration
The data field corresponds to the fields in the source data items.
The label will be used whenever the field is referenced or presented to the user.
If the field contains a numeric value, the precision value defines the number of decimal digits.
If the option "Calculation field" is enabled, the value of the dashboard field is determined via calculation expression (Calculation expression). This may be used, for example, to convert a unix timestamp into a formatted date.
The input value of the calculation is each source data item. Hence, the field values can be accessed via the {DATAFIELDNAME} syntax.
Example: The value of the field "volume" should be trippled, the expression would be $calc(3 * {volume}).
