Additional time series can be configured in display group plots. These series are found via attribute functions in the <locationFunctionEquals selected=@ATTRIBUTE_ID_A@ additional="@ATTRIBUTE_ID_B@"> of the selected time series and the additional time series. When the attribute functions evaluate to the same value the additional time series are added as invisible by default. When additional time series are available the icon of the visibility dialog will change which shows that invisible time series are available and can be made visible.
When it is desired that the additional time series are added only for the same locations then all locations should have an attribute that is equal to their id for example LOC_ID and the locationFunctionEqualselement can be used as follows:
<locationFunctionEquals selected=@LOC_ID@ additional="@LOC_ID@">
There is an extra option to show the additional time series in a separate sub plot to make sure there are no plots with incompatible parameter combinations.
