Failures/Suspensions HistogramThe Failures/Suspensions Histogram shows the frequency distribution of the failures and suspensions in the data set. The data set is separated into time intervals, and the number of failures/suspensions that fall into each time interval are plotted in a bar chart. This chart has two display options:
