Cumulative frequency graphs present a plot of flow or concentration on the x-axis, against the frequency of occurrence of that value or lower on the y-axis. This may be thought of as the frequency of compliance with any given value. While time-series graphs provide an overview of behavior, cumulative frequency graphs provide a more informative summary of treatment performance.
Note: To view or save these model outputs after the run, you need to select Flow Based Cumulative Frequency Graph to record before you run.
