Body Params

A derived signal.

string

Label of the derived signal. This appears in the Library when browsing for derived signals, and when a derived signal is used in any Exabel feature (e.g. chart, dashboard). It can also be used to reference this derived signal in a second derived signal.

This is required when creating a derived signal. Must be a valid Python identifier between 1-100 characters, match the regex ^[a-zA-Z_]\w{0,99}$, and cannot be a Python keyword.

A DSL expression describing the signal transformations to apply. For more information, see the DSL reference.

The human readable name of the signal.

metadata

Additional metadata to control formatting (decimals and units).

Note: this is only used today when a signal is added to a dashboard table. This will be phased out in favour of providing formatting controls in the Exabel features (charts, dashboards, etc.) where signals are used.
