Wind direction, north behavior
« on: February 23, 2008, 09:13:33 PM »
In my area, when the wind is northerly, it seems the graph gets a little ugly when it flips between displaying north and the top or the bottom of the graph, it seems it should be smart enough to know that it shouldn't draw the connecting line 350 degrees if the wind moves from 10 to 350 degrees?


The wind graph for a southerly wind looks like noise in this graph, it swings up and down North to North, rather just staying on one end of the spectrum?

Does this make sense?

Control Panel > Graph Setup > Windspeed Setup Tab

Select "Plot as dots" if you don't like lines, or SENWS to have N in the middle of the graph if your wind is usually swinging around North.

Otherwise it's inevitable that a value swinging around 360/0 is going to plot a line as it transitions.

thanks a lot for the hint, plotting the 10 min avg also helped

Hello..

Just out of curiosity...where on your house is your anenometer Mounted? is it on the side of the house near the roof peak?  is it on the top part of the roof?  is it mounted next to your chimney?

if you could also post a picture that would be great to see.

also how far above ground level is your anenometer?

is your house built on any kind of hill or slope land...or is all flat land around the home?

sorry for so many questions, but I am curious to know this information.

Thank you,..Chris
