Unlike the histogram which has a limited number of bins, ideally the cumulative frequency plot should have one point for every data element.
Even in small datasets (for example a @mymath{200\times200} image) this will result in an unreasonably large number of points to plot (40000)! As a result, for practical reasons, it is common to only store its value on a certain number of points (intervals) in the input range rather than the whole dataset, so you should determine the number of bins you want when asking for a cumulative frequency plot.
In Gnuastro (and thus the Statistics program), the number reported for each bin is the total number of data points until the larger interval value for that bin.

So as a summary, both the histogram and cumulative frequency plot in Statistics will work with bins.
Within each bin/interval, the lower value is considered to be within then bin (it is inclusive), but its larger value is not (it is exclusive).
