Ordinate \Or"di*nate\, a. [L. ordinatus, p. p. of ordinare. See
{Ordain}.]
Well-ordered; orderly; regular; methodical. "A life blissful
and ordinate." --Chaucer.

Ordinate \Or"di*nate\, n. (Geom.)
The distance of any point in a curve or a straight line,
measured on a line called the axis of ordinates or on a line
parallel to it, from another line called the axis of
abscissas, on which the corresponding abscissa of the point
is measured.
[1913 Webster]

Note: The ordinate and abscissa, taken together, are called
coordinates, and define the position of the point with
reference to the two axes named, the intersection of
which is called the origin of coordinates. In a typical
two-dimensional plot, viewed on a plane graph in its
normal orientation with perpendicular axes, the
ordinate is the vertical axis; when the axes are
labeled as x and y, it is the y-axis. See {Coordinate}.
[1913 Webster PJC]


Ordinate \Or"di*nate\, v. t.
To appoint, to regulate; to harmonize. --Bp. Hall.
