The Risk Gantt Chart displays risk critical tasks which are:
1. Tasks originally on the critical path, but can be combined with other risk critical tasks, resulting in slack time for each of the tasks.
2. Tasks not originally on the critical path, but during the simulation they could not be completed prior to the estimated project completion date.
3. Tasks which are 100% certain to finish later than their most likely completion date.
4. Tasks not originally on the critical path, but during the simulation they appear on the critical path more than a user-specified percentage of time.
