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 Bubble Plot task, you must assign a column to the X variable, Y variable, and Size variable roles.
Option Name
Description
Roles
X variable
specifies the variable for the X axis.
Y variable
specifies the variable for the Y axis.
Size variable
specifies a numeric variable that controls the size of the bubbles. The minimum and maximum values automatically provide the range that is used to determine bubble size. You can set these values on the Options tab.
Color response variable
specifies the numeric variable that is used to map colors to a gradient legend.
Group variable
specifies the variable that is used to group the data. The bubbles for each group are automatically distinguished by different colors.
Note: If you also assign a variable to the Color response variable role, the group variable is ignored.
Label variable
specifies the values to use as labels for each data point. If you assign a variable to this role, the values of that variable are used for the data labels. If you do not assign a variable to this role, 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.
