specifies one or more plot requests. Each plot request specifies the variables to plot and produces a separate cell. All variables must be in the input data set. Multiple plot requests are separated with blanks. You can plot character or numeric variables. A plot request can be either of these:

y-variable*x-variable

plots the values of two variables.

y-variable: variable plotted on the left vertical axis.

x-variable: variable plotted on the horizontal axis.

(y-variable(s))*(x-variable(s))

plots the values of two or more variables and produces a separate cell for each combination of Y and X variables. That is, each Y*X pair is plotted on a separate set of axes.

y-variable(s): variables plotted on the left vertical axes.

x-variable(s): variables plotted on the horizontal axes.

If you use only one y-variable or only one x-variable, omit the parentheses for that variable, for example,

plot (temp rain)*month;

This plot request produces two cells, one for TEMP and MONTH and one for RAIN and MONTH.

Optional Arguments

ATTRID= variable: specifies the value of the ID variable in an attribute map data set. You specify this option only if you are using an attribute map to control visual attributes of the graph. For more information, see Using SG Attribute Maps to Control Visual Attributes.

COLUMNS= n: specifies the number of columns in the graph.

DATALABEL <= variable>: displays a label for each data point. If you specify a variable, the values of that variable are used for the data labels. If you do not specify a variable, the value of the Y variable is used for the data label.

ELLIPSE <= (options)>

adds a confidence or prediction ellipse to the scatter plot. options can be one or more of the following:

ALPHA= n: specifies the confidence level for the ellipse. Specify a number between 0.00 (100% confidence) and 1.00 (0% confidence).

Default:PREDICTED

Restriction:To use this option, all of the X and Y variables must be numeric.

Interaction:The GROUP option does not affect the creation of ellipses. The SGSCATTER procedure always uses all of the data points to calculate the confidence or prediction ellipse.
