<!--
    @component Metric plot wrapper with user scope selection; used in job detail view

    Properties:
      - `job Object`: The GQL job object
      - `metricName String`: The metrics name
      - `metricUnit Object`: The metrics GQL unit object
      - `nativeScope String`: The metrics native scope
      - `scopes [String]`: The scopes returned for this metric
      - `width Number`: Nested plot width
      - `rawData [Object]`: Metric data for all scopes returned for this metric
      - `isShared Bool?`: If this job used shared resources; will adapt threshold indicators accordingly in downstream plots [Default: false]
