By selecting filter "Rain_Gauges" from example above the qualifiers panel will be visible because there are filters based on qualifier constraints defined, but it is empty because the selected filter is not based on qualifier constraints:

...

For instance the qualifier nodes "Analyse code" and "Compartiment" from the configuration above will not be shown in the tree because all data just has "PTB" and "OW" (shown as "Opp. Water") as qualifiers:

Change qualifier labels

When using the (right click) context menu in the qualifier tree it is possible to change the labels of the qualifiers by making a selection of the attributes.

...

But selecting qualifiers over different groups results in selecting less time series:

Qualifier summation

The icon of a qualifier node indicates what kind of time series selection should be made. The folder icon as shown in the picture above means show all time series separate.

The icon can be clicked to change to a summation icon which mean a total should be calculated of the selected time series with qualifiers belonging to the same group:will result in a summation of all time series that only differ on a qualifier within that group. Those time series will be replaced by 1 time series which contains the total value of the summation. A total will appear as 1 time series in the Time Series Dialog:

Qualifier Aggregation

Within a time series set qualifierAggregation can be specified, this combines all time series that have the (in the same time series set) specified qualifiers together to one time series. Aggregation can be done by sum, mean, min or max.Image Removed
