Configuration example
SelectionMinimumFunctionTest 1.00 default.xml
<transformation id="minimum function test">
<selection>
<minimum>
<inputVariable>
<timeSeriesSet>
<moduleInstanceId>SelectionMinimumFunctionTest</moduleInstanceId>
<valueType>scalar</valueType>
<parameterId>H.tidal</parameterId>
<locationId>H-2010</locationId>
<timeSeriesType>external historical</timeSeriesType>
<timeStep unit="minute" multiplier="15"/>
<relativeViewPeriod unit="day" start="0" end="365"/>
<readWriteMode>editing visible to all future task runs</readWriteMode>
</timeSeriesSet>
</inputVariable>
<selectNumberOfLowestMin>3</selectNumberOfLowestMin>
<outputVariable>
<timeSeriesSet>
<moduleInstanceId>SelectionMinimumFunctionTest</moduleInstanceId>
<valueType>scalar</valueType>
<parameterId>H.updated</parameterId>
<locationId>H-2010</locationId>
<timeSeriesType>external historical</timeSeriesType>
<timeStep unit="nonequidistant"/>
<relativeViewPeriod unit="day" start="-5" end="15"/>
<readWriteMode>add originals</readWriteMode>
</timeSeriesSet>
</outputVariable>
</minimum>
</selection>
</transformation>
In this example:
- The three lowest minimum values are returned by the output time series.
