A contour line of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensional graph of the function f parallel to the-plane
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value.[1][2] It is a plane section of the three-dimensional graph of the function {\displaystyle f(x,y)}f(x,y) parallel to the {\displaystyle (x,y)}(x,y)-plane. More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value.
