the graph line you will find will update
and the data on the right will update as you move the mouse cursor over the line
but the actual data will only update when you go to view that screen
or when its set to update to a web page
as the solar data generally is not important for fast updating like normal weather data is
(windspeed/direction )
(and most weather station types it only updates every minute)
I have fixed the wind direction value on the real time graph update rate in build 7
