In the Limit values for Global Variable dialog window both warning
and intervention limits can be defined for the value of the global variable.
If you have defined the limits, then these will be shown in the graph in
orange for warning limits and red for intervention limits. However,
whether these limits are observed is not monitored, i.e., a breach of these
limits does not trigger any action.
