A cross-plot, also called crossplot or cross plot, [1] is a type of plot used in Earth science to describe relationships for two or more variables. [2] Most plots referred to as cross-plots are scatter plots, [1] but combinations of different charts and diagrams can be common (e.g. histograms). [3] The axes of the plot are commonly linear, but may also be logarithmic. [4]
Cross-plots are used to interpret geophysical (e.g., amplitude versus offset analysis), geochemical, and hydrologic data.
