Definition of abscissa in English English dictionary
The first of the two terms by which a point is referred to, in a system of fixed rectilinear coordinate (Cartesian coordinate) axes. The abscissa is also known as the "x" coordinate of a point, shown on the horizontal line, with the ordinate, also known as the "y" coordinate, shown on the vertical line
The point (3,2) has 3 as its abscissa and 2 as its ordinate.
The value corresponding to the horizontal distance of a point on a graph from the Y axis The X coordinate
the horizontal axis (x-axis) of a graph or plot: "The year is shown on the abscissa, while the rainfall is shown on the ordinate (y-axis)"
The horizontal coordinate in a two-dimensional system of rectangular Cartesian coordinates; usually denoted by x; also, the horizontal axis of any graph
A line, or part of a line, drawn horizontally on a graph Measures the distance per second on spirogram tracing
the name given to the horizontal axis in a set of two-dimensional coordinates Commonly referred to as the x-axis
One of the elements of reference by which a point, as of a curve, is referred to a system of fixed rectilineal coördinate axes
One of the elements of reference by which a point, as of a curve, is referred to a system of fixed rectilinear coordinate axes. When referred to two intersecting axes, one of them called the axis of abscissas, or of X, and the other the axis of ordinates, or of Y, the abscissa of the point is the distance cut off from the axis of X by a line drawn through it and parallel to the axis of Y. When a point in space is referred to three axes having a common intersection, the abscissa may be the distance measured parallel to either of them, from the point to the plane of the other two axes. Abscissas and ordinates taken together are called coordinates. -- OX or PY is the abscissa of the point P of the curve, OY or PX its ordinate, the intersecting lines OX and OY being the axes of abscissas and ordinates respectively, and the point O their origin
{i} distance of a coordinate from the the vertical axis (y-axis) of a graph measured on a line which is parallel to the horizontal axis (x-axis)
