}

The display properties for a Field.

These are used by the Grafana frontend to modify how the field is displayed.

Fields

display_name: Option<String>

Overrides Grafana default naming.

This should not be used from a datasource.

display_name_from_ds: Option<String>

Overrides Grafana default naming in a better way that allows users to further override it easily.

This should be used instead of display_name when used from a datasource.

path: Option<String>

An explicit path to the field in the datasource.

When the frame meta includes a path, this will default to `${frame.meta.path}/${field.name}.

When defined, this value can be used as an identifier within the datasource scope, and may be used as an identifier to update values in a subsequent request.

description: Option<String>

Human readable field metadata.

writeable: Option<bool>

Indicates that the datasource knows how to update this value.

filterable: Option<bool>

Indicates if the field’s data can be filtered by additional calls.

unit: Option<String>

The string to display to represent this field’s unit, such as “Requests/sec”.

decimals: Option<u16>

The number of decimal places to display.

min: Option<f64>

The minimum value of fields in the column.

When present the frontend can skip the calculation.

max: Option<f64>

The maximum value of fields in the column.

When present the frontend can skip the calculation.

mappings: Vec<ValueMapping>

Mappings from input value to display string.

thresholds: Option<ThresholdsConfig>

Mappings from numeric values to states.

links: Vec<DataLink>

Links to use when clicking on a result.

no_value: Option<String>

An alternative string to use when no value is present.

The default is an empty string.

custom: HashMap<String, Value>

Panel-specific values.
