PaulS:
I think that your fundamental assumption, that light level correlates to time, is flawed.
I just put that 1 pm and 2 pm there as a test, I am not trying to correlate light with time, I am trying to map an average value of my photocells to an elevation of the sun, that is my problem but my problem is that the value i get a 10 AM over lap with the values i get at 2 PM, so how i do i display this seperately? like example i get 500 at 10 am which has an angle of say 50 then i get 500 again at 2 PM but an an angle at 80. get it?
