With that sharp twist at the right I'd say these graphs are actually depicting underwire.

From 19 to 50.

Having grown up north of the arctic circle, this is a common fact of life. In mid summer, the sun never completely sets before it rises again. Blows my mind that this change are too subtle to notice closer to the equator.

And here at the equator it’s the opposite. Our days are almost always 12 hours long. They only vary by an hour or so throughout the year. Same temperature all year too.

And night/morning comes fast. When I've been to places near the equator, it always catches me off-guard. I'm used to daylight only beginning to dim, and thinking, "ah, I need to account for it being dark outside in a couple hours".

Not so near the equator, sunlight just turns off abruptly.

it would be interesting to see these graphs on the same y-axis scale to show the relative time differences between latitudes.

Reminds me of one of my favorite jokes that sounds racist until you think about it:

Q: What's the drawback to a one-night stand with an Inuit girl?

A: When the sun comes up, she's six months pregnant.

(Granted, it's only funny to me because I occasionally work in Greenland.)

Those charts are arranged terribly.

You are asking a lot from MATLAB.

[–] [email protected] 4 points 1 year ago

Don't blame matlab its the worlds best engineering language as long as someone else is paying for it

[–] [email protected] 1 points 1 year ago

MATLAB can’t sort?

[–] [email protected] 2 points 1 year ago (1 children)

How do you want them to be arranged?

[–] [email protected] 1 points 1 year ago

Presumably high-medium-low. Sorting them as medium-low-high is a little weird.

[–] [email protected] 4 points 1 year ago

It's interesting. I built a weather app for Android earlier in the year and started noticing that each day, the sunrise and sunset changed by roughly one minute.

I never noticed that before.

http://clearoutside.com will show you a lot of information about your latitude, such as annual darkness.
