For any defined time series the user can use the keystroke functions (F2) to toggle the display for box & whisker plots (Alt-1) or show the lines as Cumulative Distribution Functions (CDF's) (Alt-C). The user can also compute average values for each series for the data within the x axis minimum and maximum (Ctrl-A). These values are also copied to the clipboard to be easily copied into Excel© integrate the series (X*Y*User specified conversion factor).

Ctrl-I allows the user to integrate curves using a simple multiplication, where x is time, and y is Q in m3/s as shown in Analysis and Statistics#Figure 1. However, as the time is in days the user must adjust the units between days and seconds when prompted.

Line statistics by time block may also be displayed with the keystroke Alt-S. This is similar to a box and whisker plot data, but it generates a set of statistics. When the user wants to analyze each line by month they should select "1 M". All the data is tab delimited and copied to the clipboard. The statistics generated are the average, standard deviation, minimum, maximum, lower quartile, median, upper quartile, standard error 95% and confidence interval. ( See Analysis and Statistics#Figure 2)
