The Y and X columns become the y and x coordinates of the bubbles in the plot. These values can be continuous or categorical (nominal or ordinal).
ID variables identify rows that should be aggregated and shown as a single bubble. The default coordinates of each bubble are the averaged x and y values, and the default size of each bubble is the sum of the sizes of all aggregated members. See Specifying Two ID Variables.
Maintains separate coordinates, sizes, and colors for each unique time period. The bubble plot shows these values for a single time period. For example, if the Time column contains years, the bubble plot is updated to show data by each year. See Specifying a Time Variable.
Controls the size of the bubbles. The area of the bubbles is proportional to the Size value. There is a minimum bubble size, to keep bubbles visible, even if the size value is zero. If Size is left blank, the default bubble size is proportional to the number of rows in that combination of Time and ID.
After you click OK, the Bubble Plot report window appears.
