What is the term for a political model used to compare political opinions?

"Political spectrum" is the term for a political model used to compare political opinions.

The political spectrum alludes to the range of political positions or assessments that exist from the dynamic left wing to the traditionalist conservative.  

In short, the political spectrum instructs us that contrary energies are the equivalent and the equivalent are alternate extremes.  

Each individual lies some place along this political spectrum, however many don't know precisely where they lie, or they name themselves as something that they may not be altogether.
