in order to visually express this argument, nolan came up with a two-axis graph. one axis was for economic freedom and the other was for personal freedom, with the scale on each of the two axes ranging from zero (total state control) to 100% (no state control). 100% freedom in economics would mean an entirely free market ("laissez-faire"); 100% freedom in personal issues would mean no government control of private, personal life. by using the scale on each of the two axes, it was possible to graph the intersection of the amount of personal liberty and economic liberty a person, political organization, or political philosophy advocates. therefore, instead of classifying all political opinion on a one-dimensional range from left to right, nolan's chart allowed two-dimensional measurement: how much (or little) government control a person favored in personal and economic matters.
