Max Threshold definition
ThresholdWarningLevels
Different threshold warning levels can be defined. They need to be in order of increasing severity. First level defined is always the no-threshold-cross level.
Optionally a missingDataThreshold can be defined. Setting a different cell background color for this allows to differentiate easier between no threshold crossing and no data available. If missingDataThreshold is defined it must precede the thresholdWarningLevels. Example:
