windrose

Dear users,

                     Attached is a windrose diagram created by using https://sourceforge.net/project/showfiles.php?group_id=239240&package_id=290902 . Can any one tell me if the numbers displayed in the attached plot is % of wind directions in each category? or are they represent some other numbers?

Sudheer,

That's correct. The total length of the bars is the percentage of time that
the wind is blowing *from* that direction.
See my implementation here:
https://github.com/phobson/python-metar/blob/master/metar/graphics.py#L135

Side note, you're emails are consistently formatted pretty strangely and
can be difficult to read. Perhaps stick with the same font that is in your
email signature?

Just a thought:

Shouldn’t the bars terminate with a arc rather then a straight line? What value should one reading this diagram look at? The one at the center of the “bar” or the “corners” these values can be quite different.

Thank you Paul,

I think the font issue is the mischief of Yahoo. I think I should send mail in text mode rather than html then the issue will not be there I hope. The signature is in normal text mode I saved. Please revert back if my mail shows font issues again so that I can try some thing different. However when I see it in Yahoo there is no issues though…

with best regards,

Sudheer
