In the Limits for common variable dialog window both warning and
intervention limits can be defined for the value of the common variables.
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.
