open-in-new
<p>A cross-plot, also called crossplot or cross plot, is a type of plot used in <a href="/facts/Earth_science/rQsXCSbM">Earth science</a> to describe relationships for two or more <a href="/facts/Variable_(mathematics)/VbQlrvKz">variables</a>. Most plots referred to as cross-plots are <a href="/facts/Scatter_plot/n03xBtBL">scatter plots</a>, but combinations of different charts and diagrams can be common (e.g. <a href="/facts/Histogram/oMmvqGEA">histograms</a>). The axes of the plot are commonly <a href="/facts/Linear/fChtg3KC">linear</a>, but may also be <a href="/facts/Logarithmic_scale/CvIGK5TQ">logarithmic</a>. </p><p>Cross-plots are used to interpret <a href="/facts/Geophysics/ywVQ1sAQ">geophysical</a> (e.g., <a href="/facts/Amplitude_versus_offset/lbWVuVeb">amplitude versus offset</a> analysis), <a href="/facts/Geochemistry/05094gDu">geochemical</a>, and <a href="/facts/Hydrology/Xh727cnE">hydrologic</a> data. </p>
