Assigning Data to Roles

You can subset the data in the input data set by applying an SQL WHERE clause. In the Where string box, enter your valid SQL syntax. Operands that are character strings must be enclosed in single or double quotation marks. To view this WHERE clause with the resulting graph, select the Include as footnote check box.
To run the Scatter Plot task, you must assign columns to the X variable and Y variable role.

Description
Roles
X variable
specifies the variable for the x axis.
Y variable
specifies the variable for the y axis.
Group variable
specifies a variable that is used to group the data. The plot elements for each group value are automatically distinguished by different visual attributes.
Marker label 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, then the values of the Y variable are used for the data labels.
URL variable
specifies a character variable that contains URLs for web pages to be displayed when parts of the plot are selected within an HTML page.
Fit Plots
Note: This is available only if you assign numeric variables.
Regression
creates a plot with the fitted regression line. You can specify whether to include the confidence limits for means and the prediction limits for the individual predicted values. The Alpha option specifies the confidence level for the confidence limits. The Degree option specifies the degree of the polynomial fit.
Loess
creates a fitted loess curve. You can specify whether to include the confidence limits. The Alpha option specifies the confidence level for the confidence limits.
PBSpline
creates a fitted penalized B-spline curve. You can specify whether to include the confidence limits for means and the prediction limits for the individual predicted values. The Alpha option specifies the confidence level for the confidence limits.
