The horizontal axis of a graph is also known as the x axis. Typically, the horizontal axis describes a quantity that changes in a predictable fashion.

This variable is deliberately controlled by the experimenter in order to determine the effects that change has on other variables.
1 With a chart, the y-axis is the vertical data that is typically on the right-side of the chart. 2  In computer graphics, if you wanted to draw a horizontal line the x-axis can be used to determine the start and end point of the line. 3  Drawing a two-dimensional object would require only the x-axis and y-axis.
