• Probability Plot–A plot of the probability of failure over time based on a specific distribution. For life data analysis, these plots are usually called Weibull probability plots.

• Reliability vs. Time Plot–A plot of the reliability over time.

• PDF Plot–A plot of the probability density function (pdf).

• Failure Rate vs. Time Plot–A plot of the failure rate over time.

• Contour Plot–When MLE is the parameter estimation method, a graphical representation of the possible solutions to the likelihood ratio equation for comparing different data sets.
