This page contains a series of scatterplot examples illustrating the available varieties and options. These examples all use ploticus's proc scatterplot. Clickmaps are supported for scatterplots.

See also the scat prefab examples.


Example 1

scatterplot1

This example shows the correlation between two variables. The 1-D distribution for each variable is shown along each axis. Duplicate data points are offset slightly (the cluster option) to show duplicity.


Example 2

scatterplot10

Correlation scatterplot showing regression line and error bars on the points.


Example 3

scatterplot8

This illustrates how multiple points can be displayed using the clustering option. Size, color, "transparency", and shape of the points are all user-controllable, as is the distance of clustering.


Example 4


scatterplot3

Points may be marked with a variety of geometric symbols and characters/text, in a variety of colors. Point symbols may be solid (filled) or transparent (not filled).


Example 5


scatterplot3a

The size of point symbols may be driven by a data field, allowing display of a 3rd variable.


Example 6


scatterplot5

An example where data text is shown instead of a point symbol. This may be useful in identifying outlier cases.


Example 7


qual

An example showing scores over time. Case identifiers are shown at bottom using a second invocation of proc scatterplot.


Example 8


multiscat

A full-page example showing an array of scatterplots.

Single variable (1-D) distributions

Example 9


scatterplot6

A 1-D scatterplot showing instances over time. Instances are denoted by lines in the top panel, and by names in the bottom panel. 1-D distributions usually work better for scattered data points; when there is significant duplication a histogram (bar graph) is more effective.


Example 10


beeswarm

A beeswarm-like distribution plot. In this example proc scatterplot clustered the bars horizontally.
