Depiction of data point relationships in a two-dimensional drawing. The relationship , most commonly between two set of numbers, displays in several different ways. It can be a line, a curve, a series of bars, or some other group of symbols. A common drawing starts with an independent variable represented on the horizontal line, called the X-axis. A dependent variable goes on the vertical line, or Y-axis. The X and Y axis intersect perpendicular at a point called the origin. Each axis is calibrated in some unit value for the quantities to be represented. Taken to mean the same as ‘chart’.
