What you need to do, is to either create a new column to be used for the size or create a Transform variable when you specify the platform selections. The formula to use for the new column or the transform column is

`If(:Group=="ECJ_6A3T", 9, 2);`

Then use the new column as the Size specification variable. Since Group values with the value of "ECJ_6A3T" will have the new columns value of 9, and the Group values for "POR" will have the new column's value of 2, JMP will make the size of the ECJ_6A3T dots the larger of the 2.
