Definition

A contour plot (also contour map) is a graphic representation of the relationships among three numeric variables in two dimensions. Two variables are for X and Y axes, and a third variable Z is for contour levels. The contour levels are plotted as curves; the area between curves can be color coded to indicate interpolated values.
[SAS, 2008]


Types of contour plots

Meteorology

The map shows the analysis of the weather condition. The isobars represent lines of constant barometric pressure.

Physical geography and oceanography

Ocean bottom topography, also known as bathymetry, is the measurement of the depth of large bodies of water.

Thermodynamics, engineering, and other sciences

A contour map with contour lines.
