Compass rose not working.

Post by BandAidUK »

The compass rose doesn't seem to be working. I've tried both 1.9.2 and 1.9.3 beta but still have this problem.

I can see there's something there - if you look at the attached screenshot you can see the "W" line of the rose is thicker. This "thicker line" moves about from time to time.

I have an Oregon Scientific WMR 180A and am running it as a WMR 100 on Cumulus. Everything else works brilliantly.

Any ideas?

The wind rose can only display something useful if its given useful data to display (as in: data with a suitable profile for this type of wind rose). If you haven't had sufficient wind readings in more than one adjacent sector since you started Cumulus up, it will only be able to plot lines, rather than areas. It looks to me like you have also had a few NE readings along with your mainly W readings, and no other significant readings in any other directions.

You can see what values the wind rose is plotting by looking at the <#wdirdata> and <#wspddata> web tags.
