However I did not do so for the Windrun (don't ask why, I forgot).
The Wind has basically three important charts/reports: The WindRose graph, The WindRun graph and the YADR WindRun report (with the legend).
All three have a legend for which the intervals are configurable with parameters:
Code: Select all
WindRoseNrOfWindforceClasses=6
WindRoseMaxWindSpeed=60
WindrunClassWidth=75
Especially the windrun requires configuring when the user uses imperial units (mi, kts) and the user is free to choose the class width which will differ depending on the region of the station. The default value uses a 75 km windrun class width which fits Dutch environment.
A related item is the nr of windrose compass sectors. Those are taken from Cumulus.ini, section [Display], parameter NumWindRosePoints.
However to get the compass letters right read the wiki.
