Plot Description:

This plot presents a histogram of the change in some observed variable over a given number of hours. The histogram is constructed by computing the 99.9th percentile of the absolute value of the change in the variable over the given number of hours. This max value is then used to create a histogram with bins of a given width. The histogram is then normalized by the number of years of data available.
