• Divide - allows a value to be given with which original data is divided for a defined time span.
• Replace - allows a value to be given that replaces the original data for a defined time span.
• Missing - allows the original values with missing data for a defined time span.
• Time Shift Typical Profile - allows a time increment to be defined with which the original data is to be shifted (not yet available2022.01).

Once a modifier has been defined it cannot be changed. At any time the modifier can be enabled and disabled, or deleted.
Configuration of the Time Series Modifiers Display
As the time series modifiers is a central component to the Delft FEWS system, its configuration is quite simple. No additional configuration need be added. The display does require preconfigured displays to be defined using the Display Groups configuration as the time series defined in these display groups are available for applying modifiers to.
Making this display available only requires the relevant class be called from the Explorer. It is added as an explorer Task.
An example of the configuration is provided below
| Code Block | ||||
|---|---|---|---|---|
| ||||
<explorerTask name="Modifier Display">
<iconFile></iconFile>
<mnemonic>X</mnemonic>
<displayConfigFileName>ModifiersDisplay</displayConfigFileName>
<toolbarTask>true</toolbarTask>
<menubarTask>true</menubarTask>
<accelerator>ctrl X</accelerator>
<loadAtStartup>true</loadAtStartup>
</explorerTask>

Note that the use if Icons and Mnemonics, as well as the name of the display will depend on the configuration.
