Editing Scatter plot (section)

== Scatter plot matrices ==
For a set of data variables (dimensions) ''X''<sub>1</sub>, ''X''<sub>2</sub>, ... , ''X''<sub>''k''</sub>, the scatter plot matrix shows all the pairwise scatter plots of the variables on a single view with multiple scatterplots in a matrix format. For {{mvar|k}} variables, the scatterplot matrix will contain {{mvar|k}} rows and {{mvar|k}} columns. A plot located on the intersection of row and {{mvar|j}}th column is a plot of variables ''X''<sub>''i''</sub> versus ''X''<sub>''j''</sub>.<ref>[http://www.itl.nist.gov/div898/handbook/eda/section3/scatplma.htm Scatter Plot Matrix] at itl.nist.gov.</ref> This means that each row and column is one dimension, and each cell plots a scatter plot of two dimensions.{{fact|date=April 2024}}

A '''generalized scatter plot matrix'''<ref>{{cite journal|last1=Emerson|first1=John W.|last2=Green|first2=Walton A.|last3=Schoerke|first3=Barret|last4=Crowley|first4=Jason|title=The Generalized Pairs Plot|journal=Journal of Computational and Graphical Statistics|date=2013|volume=22|issue=1|pages=79–91|doi=10.1080/10618600.2012.694762|s2cid=28344569}}</ref> offers a range of displays of paired combinations of categorical and quantitative variables. A [[mosaic plot]], [[fluctuation diagram]], or faceted [[bar chart]] may be used to display two categorical variables. Other plots are used for one categorical and one quantitative variables.
