Let's assume that the three components A, B and C follow failure distributions Weibull(Beta=1.5,Eta=1000), Weibull(Beta=1.1, Eta=800) and Exponential(MTTF=3000). The reliability for each components and the system at mission time =100 hours is shown in the figure below.
There are several plots available for analytical RBD and fault tree analysis.
At the system level, there are four plots available as shown in the following:
Unreliability vs. Time
Reliability vs. Time
Probability Density Function
Failure Rate vs. Time
For the metrics, three kinds of reliability importance plots are available:
Reliability Importance vs. Time
Static Reliability Importance
Static Reliability Importance(Tableau)

At the block level, four kinds of plots are available:
Block Unreliability vs. Time
Block Reliability vs. Time
Block Probability Density Function
Block Failure Rate
