A graph is normally shown on a two-dimensional medium and thus the simplest graphs to interpret that demand the least technical training for both the presenter and the observer are also formed in two dimensions. The abscissa is a term related to a two-dimensional graph and the goal of a graph is to visually represent a set of data in a way that all of the data can be seen simultaneously processed by the interpreter. Further Explanation: Abscissa and Data Representation The point (-3, 3) has a distance of -3 from the origin on the x-axis and a distance of 3 from the origin on the y-axis. We will illustrate the Abscissa and Ordinate using different graphs.įigure 3 – The point (-3, 3) in the cartesian planeįigure 3 shows the two-dimensional cartesian plane, The horizontal axis is in the range -4 to +3 and whereas the vertical axis has a range from 0 to +3, There is a point at the place (-3, 3), The inscription (-3, 3) means that the point has abscissa of -3 and the ordinate of 3. By using the abscissa and the ordinate a pattern or a trend of the data can also be extracted by looking at the points. In mathematics, the abscissa and the ordinate refer to the first and second coordinates of a point in a Cartesian coordinate system. Both the Abscissa and Ordinate define the locations of the point in the Cartesian two-dimensional plane. The length of a point from the y-axis rising with the x-axis is named abscissa. An ordered pair is operated to indicate a point in the Cartesian plane and the first coordinate (x) in the plane is named the abscissa, and the second coordinate (y) in the plane is the ordinate. Y is the ordinate, y-axis, or vertical axis here and similarly, x is the abscissa, x-axis, or horizontal axis here. On the other hand, the ordinate which is also named the y-axis is the length of a point from the x-axis rising with the y-axis.įor instance, assume (x, y) is given as an ordered pair. The abscissa is also called the x-axis of the point and is the distance of a point from the y-axis, rising with the x-axis. The detail of their differences is explained in the below paragraph. The main difference between the abscissa and ordinate is that the abscissa refers to the y-axis and the ordinate refers to the y-axis. Figure 1 – Example of Abscissa and Ordinate.
