About PDF Plot

The Probability Density Function (PDF) plot is a lin-lin plot that counts the number of failures between certain time periods, creating a curve that estimates how many failures you can expect to occur at a given number of time units. This plot shows Probability vs. time. The term Probability is used here to describe the percent of the population that failed at the particular value of time (t). A PDF plot helps you to answer a question such as, "What is the chance of a member of the population failing at exactly the time in question?"

Probability Density Function plot

PDF plot shows the curve fit of the data. It answers the question, "Based on the curve fit, what is the probability that failure will occur below or above a certain value?" The chart is a graphical representation of the data. It shows the variance or spread of the data.

Note: Interaction with charts is not available on touch-screen devices.
