It looks like your ability of abstracting is pretty low. 😋 I both cases those are Time series (you cannot represent accumulation without it). In case you have cumulative function, in another it is either simple f(x) =x or average skidding window. So comparison is very fair.

It is absolutely valid because it's about data representation. And it depends on purpose of this particular data reforestation. And your (and only your) assumption is that purpose of this particular case is to show that North got more snow then South. And like I pointed out this is not always the case. So you are introducing a big no-no to data representation - - inconsistencies. While country order is always consistent.

I am very familiar with vectors in general and gradients in particular. Try to represent 3D gradient on weather map.

Nope, you are making too many assumptions. Data on the table shows everything. Taking into account how weather models wor and it discrete nature tables or N-Dimensional matrices table are very natural in this area.

It's normal content -- when you following your portfolio you look at sliding window of particular stock(s) behavior trying to find moment when to sell and when to buy. And does not matter if data represented in a graphical format or as a table.

And it represented it perfectly. And not always northern areas get more snow. So you assumption is incorrect. Are familiar with conception of gradient? Yeah, it's a math conception but it's heavily used in meteorology. Very often days are presented to reflect gradient of something. And sometimes color is used to reflect gradients.

And stock prices should be ordered by stock price, correct?

And one of them is natural order of recording/creation. Nothing wrong with it. It's called time series.

Like I told in chat I am your neighbor and I have some extra (trying to keep like this).

Did you get insulin? I've send a chat request yesterday.

If I am mistaken, there is a pickup track with cones and person stays on a special step and just put cones behind truck while truck is going slowly. Collection of cones is done in reverse.
