<P> The Nolan Chart is a political spectrum diagram created by David Nolan in 1969 . The chart divides human political views into two vectors--economic opinion and personal opinion--to produce a type of Cartesian chart . It expands political view analysis beyond the traditional "left--right" line, which measures politics along a one - dimensional line, into a graph with two dimensions: degrees of economic freedom and personal freedom . </P> <P> The claim that political positions can be located on a chart with two axes: left - right (economics) and tough - tender (authoritarian - libertarian) was put forward by the British psychologist Hans Eysenck in his 1954 book The Psychology of Politics with statistical evidence based on survey data . This leads to a loose classification of political positions into four quadrants, with further detail based on exact position within the quadrant . </P>
