The solar analemma is an elongated figure of eight. There are three main parameters which define the shape - obliquity, eccentricity and the angle between the apse line and the line of solstice. The distance from the node, along the north-south lobes show the latitude [on Earth] at which the sun is overhead. This is a measure of the earth's axial tilt.
The distance from the vertical axis - in the east-west direction - is a measure of the difference between the time as shown by the sun's position and clock time. This is a measure of the eccentricity of the earth's orbit.

The outer circles show the difference between the two sides. The center where they join are the area they are the same. This is a great graphic way to show comparison of two things or ideas.

Analogy is a comparison of two things in order to show how they are similar. An analogy compares two like things.
What is an analemma?
An analemma is an egg-shaped or figure-eight curve which results when the sun's position in the sky is plotted over the course of the year at the same hour of mean solar time every day.
What two things does a map scale shows?

What is the purpose for the analemma?
The analemma shows the position of the sun in the sky over the course of a year, accounting for variations in the Earth's orbit and axial tilt. It provides information about the sun's declination and the equation of time, which are important for accurate timekeeping and astronomical observations.

Is the analemma is a useful tool for locations north of the Tropic of Capricorn?
No, the analemma is a figure-eight shaped curve that shows the position of the Sun in the sky at a specific location at the same time of day throughout the year. For locations north of the Tropic of Capricorn, the analemma is not as useful because the Sun's path in the sky is closer to directly overhead during certain times of the year, making the figure-eight shape less pronounced.
Shape of the analemma if the ecliptic-equator angle increases?
The shape of the analemma would become more stretched and elongated as the ecliptic-equator angle increases. This is due to the changing angle of the Sun's declination as it moves along the ecliptic throughout the year. A larger angle between the ecliptic and the equator leads to more extreme variations in the Sun's apparent position in the sky over the course of a year.

Dark clouds overhead and a sudden cold wind.
What is the meaning of contrast and comparison?
to compare things are also show their differences(this is commonly shown but not really thought of about)
How does the analemma relate to the motion of the sun along the ecliptic?
The Sun is always on the ecliptic, even though the analemma seems to suggest that the Sun is engaged in some kind of fancy wobble. The analemma has a "figure of eight" shape. There are two components that cause this shape. First, the Sun seems to move in the north-south direction in the sky during the year, because of Earth's tilted axis. The second component is explained below. This is about the Sun's apparent daily motion East to West across the sky: The analemma is also caused because civil time or Universal Time (UTC) does not line up perfectly with "apparent solar time". Apparent solar time is what a sundial measures. UTC is almost exactly the same as "mean solar time" (the original "Greenwich Mean Time"). Our clocks are based on UTC. UTC gives the average day length over the course of a year, independent of the exact position of the Sun in the sky. The difference between these two measurements of time is caused by the Earth's tilt (again) and the Earth's elliptical orbit. So the analemma captures the Sun sometimes earlier than, and sometimes later than, what would be the theoretical 'average' position of the Sun (sometimes called "Mean Sun") over the course of a year. The analemma doesn't actually 'exist' as a physical reality. For those who are not familiar with the term, this is how you would 'observe' the analemma. Set up a camera in such a way that it will capture an image of the Sun at, for example, exactly 12:00 noon, in your local timezone. Keep the camera firmly anchored and under enough protection so that it can remain where it is for an entire year. At regular weekly intervals photograph the Sun at exactly 12:00 noon. At the end of the year, the image will show the characteristic "8" shape of the analemma. The one thing you will have to do is assure that the initial camera's view is such that the Sun will always appear in the image at noontime, all year. If you start with the Sun exactly in the middle, there may be a season when the Sun at noon will not be in the camera's view. Also you need to allow for "daylight saving" changes to your local noon, of course.
