How many spots are on the Dalmatian?

42? Which would make it the answer to life the universe and everything.

You count much better than Heid.

Just better than me, or is he correct?

True, it was a badly phrased question. So the graph plots a set of 46 items. By some counts there are 46 countries in Europe, would that be our set?

They are not countries in Europe.

The numbers on the two axes are in the same units, although obviously they are measuring different things, since the graph does not show the identity function.

Are these numbers dimensionless?
If not, would it be too much of a hint to give us the unit of the numbers?

I see 46 data points displaying a rather loose positive correlation (more of x tends to come with more of y). x values are between c. 3800 and 5300 something, while y values are between c 1800 to 4500 of the same something. It could be a graph displaying a weak correlation between prices ("in the 46 cities surveyed, the average square meter price when buying an appartment was weakly correlated with the price for a small motorbike"), or spending habits ("in our sample of 46 people, those who spend more on this tend to spend more on that also"), then the unit would be a currency. What if it is dimensionless? Anything from "of the 46 top posters at cosmoquest forum, those who posted more in the "scientific" sections also tended to post more in the Off-Topic Babbling section" to "in the past 46 years, violent deaths from at the hand of police tended to occur more often in years with more gun deaths as a consequence of usual criminal violence".

It's not obvious. The number of data points - 46 - should probably ring a bell, but doesn't, for the time being.

The units are one of the most fundamental and commonly used physical quantities. They are not metric, although the graph would look exactly the same, except for the numbers.

It has nothing to do with prices; these are very physical measurements.

The number 46 will definitely strike a note in the right community, but it is quite possible that no one here (other than myself) is familiar with that community.

The x value actually determines which points get included in the graph. If the x value falls outside of this range, then the observation is not part of this set of 46. The range was actually supposed to be slightly more restrictive, but some measurement errors were made when the set of 46 observations was originally determined. There is actually a 47th observation that, according to the latest measurements, should be included in the graph, but isn’t, because of measurement error when the list of 46 was originally compiled.

I PMed my solution to Mactep, but maybe someone else likes to climb that intellectual hill and post the next graph instead? I'll defer.

Dr. Arneb has provided a completely correct description of the graph by PM.

As he has indicated non-desire to post the next graph, we can do one of the following:

a) Continue to play, and allow someone else to figure it out.
b) Post Arneb's description publicly, and then allow someone else to post the next graph.

I think we post Dr A's answer and the first person who wants can post a new graph.

As Arneb has correctly pointed out by PM, the graph has to do with the Adirondack 46 peaks. These are supposed to be the mountains in the Adirondack range (northeastern New York) that are over 4,000 feet high, but according to the most recent survey, four of the 46 are actually a little below 4,000 feet, and there is one that is above 4,000 feet that wasn’t included on the list. However, by the rules of the 46ers club, to be a member, you must climb the original 46 peaks.

The horizontal axis shows the height of each peak above sea level, and the vertical axis shows the elevation gain on the most popular climbing route.

So as per Arneb’s wish, anyone who wants to may post a graph now.

Okay, here's one.

Hint: It has nothing to do with labias, or any other part of human anatomy.

Is the horizontal axis time?
