Absolute threshold is an independent variable which refers to the smallest intensity of a stimulus that can be detected by an observer. On a graph, the independent variable is usually plotted on the x-axis, whereas the dependent variable (which is influenced by the independent variable) is plotted on the y-axis. Therefore, a measure of absolute threshold appears on the x-axis.
