CDF Plot

The CDF plot in Distribution creates a plot of the empirical cumulative distribution function. Use the CDF plot to determine the percent of data that is at or below a given value on the horizontal axis. When a distribution is fit to the data, the cumulative distribution function for the fitted distribution is overlaid on the CDF plot.

For example, in this CDF plot, approximately 34% of the data are less than a total fat value of 10 grams.
