processdata is a prefab that allows ploticus to operate as a data processing filter, to perform various manipulations, such as summations. The result data is written to standard output. No plotting is done.

The various manipulations that can be done are described on the proc processdata man page under the action attribute.


    The only standard prefab parameters supported are data, and the parameters pertaining to the data file. By default, data is - (read from standard input).

    action is the data manipulation action to be performed. This parameter is mandatory. See the proc processdata man page action attribute for allowable actions and the descriptions.

    fields specifies one or more data fields to be involved in the operation.
