Error; or the need for alternative contours

[edit]

I think that there are some issues with this graph. Either the label that says 1 hour is meant to be 0 hours; and the label that says 23 hours is meant to be 24 hours; or the graph should have displayed the 0 and 24 hour contours instead of the current 1 and 23 hour contours. Can someone who understands the sunrise equation please produce a better graph? Thank-you --123.243.217.67 (talk) 18:13, 2 August 2014 (UTC)[reply]

That's a very good point. I based it on File:Hours_of_daylight_vs_latitude_vs_day_of_year.png and don't know much about the subject either, so any references are welcome. Cheers, cmɢʟeeτaʟκ 17:52, 18 April 2016 (UTC)[reply]
