public class WekaInstanceStreamPlotGenerator
extends AbstractTransformer

Generates plot containers from a range of attributes of the weka.core.Instance objects being passed through.
The generator merely uses the internal data representation for generating the Y value of the plot container.

Input/output:
- accepts:
weka.core.Instance
- generates:
adams.flow.container.SequencePlotterContainer

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: InstanceStreamPlotGenerator
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
 

-attributes <java.lang.String> (property: attributes)
    The range of attributes to create plot containers for; A range is a comma-separated
    list of single 1-based indices or sub-ranges of indices ('start-end'); the
    following placeholders can be used as well: first, second, third, last_2,
     last_1, last
    default: first-last
