public class TimeseriesChangeResolution
extends AbstractFilter<Timeseries>

Generates a new timeseries with a (user-defined) fixed-length interval between data points.

-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 

-no-id-update <boolean> (property: dontUpdateID)
    If enabled, suppresses updating the ID of adams.data.id.IDHandler data containers.
    default: false
 

-interval <double> (property: interval)
    The new, fixed-length interval between data points in seconds.
    default: 30.0
    minimum: 0.01
 

-polynomial <int> (property: polynomial)
    The polynomial for interpolation.
    default: 2
    minimum: 1
