Default

Input
  • inputVariable
Options
  • maxGapLength
  • defaultValue / defaultValueFunction
  • interpolationDirection
Output
  • outputVariable
Description

This tranformation fills the gaps in the time series with the default value. If defaultValue or defaultValueFunction is not defined, defaultValue 0 will be filled. If a maxGapLength is defined the gap will only be filled if the size of the gap is smaller than maxGapLength.
