Info

Although the icon descriptions are always true, there are some common assumptions that are not always correct. Following are some examples and an elaboration with details why it's not true.

-"If a timeSeries contains only missing values (also when looking outside of the view period), it will have a purple cross". This often results from the missing values not being stored in the database but are deduced (i.e, for an equidistant time steps). However, missing values that are the result of a manual adjustment are stored in the database.

-"If a timeSeries has a red cross, there are some values available, just not in this view period". The only reason a red cross is not a purple cross is because there is data stored in the database (for the timeSeries). But besides values there is are also other data stored for a timeSeries, like expired forecasts or the example shown above. These two "data" examples are not an exhaustive list and is are not meant to be, just to but they show that this assumption is not correct.

-"A red cross means I that one will see no data in the timeSeries display (or the other way around)". The selected filter determines the view period that is used to determine which data availability icon should be shown. This view period configured for a filter does not have to be the same as the view period for the timeSeries displayed in the timeSeries Dialog. If the relative view periods are the same, then the assumption can be used.

If both a data availability and validation icon is valid - both will be shown concurrently. By default only the red crosses are shown to add the additional validation icons ; add the tag to the filters file Filters file to display the additional validation icons .
