WAVE HISTOGRAM

WAVE HISTOGRAM displays a histogram of the heights of individual waves derived from the vertical displacement timeseries. Individual waves are identified using the crest-to-trough method, i.e. by calculating the crest-to-trough difference between consecutive zero up-crossings.

For buoys operated by the Navy (e.g. 067, the SNI buoy), the user can specify a height threshold and the plot will show the percentage of waves that exceed the given threshold. The default threshold is 4 meters or 13 feet.
