Hi Kiran,
To create 4 quadrants with multiple reference lines in the bubble plot, you may create a reference line firstly with X Axis. SAS VA will give a suggested value for the reference line with a value about to the average of variable assigned for X Axis. Increasing the width of the line and setting the line style if necessary, and click OK button to get first reference line created. Then similarly create the second reference line for Y Axis. After that, you will see the 4 quadrants in the bubble plot. ^_^
Feel free to contact me if you still see problem on this.
