This display provides users with a system wide overview of all threshold crossing events (as generated when you run ThresholdEventCrossing module in workflows where timeseries are generated). This display does not require any additional configuration files. It makes use of the already existing threshold configuration in the 'thresholdValueSets.xsd' and the 'thresholdDisplayConfig' that is available in the 'timeSeriesDisplayConfig.xsd'.
Activate Display
The thresholds display can be activated by adding the following explorer task in the Explorer.xml file:
...
The thresholds display does not require a display configurations file. It , it is possible to use some advanced features when a thresholdEventDisplay configuration file is added. For normal applications the display obtains all information for thresholds configuration that is already available in the ThresholdsValueSets.xml file and also in the TimeSeriesDisplayConfig.xml file.
But since Since 2019.02 specific config options for this display are available uced used to specify time series sets that can be used to find time series for target location id's belonging to the threshold events.

Firstly most information is retrieved from the ThresholdValueSets file. Here is where In this file all threshold levels are configured , and how they relate with relations to timeseries sets. For the purpose of the Thresholds Display some configuration options have been added to this the ThresholdValueSets file to control the view period and visibility of the threshold events.
...
The second place where the thresholds display retrieves configuration information is in from the TimSeriesDisplayConfig file. This file already contains an element that allows you to control the colors of the threshold values shown in the TimeSeries dialog. This section is also used by the threholds display to color the text in the Threshold Id column.

Events can either be acknowledged by selection or all none-acknowledged events can be acknowledged in one single action. Acknowledging of events can be done by clicking the right-mouse button and selecting the Acknowledge options in the pop-up menu.
